I’ve been playing Clash Royale for a long time, and honestly, I’ve made every stupid mistake possible. Upgrading the wrong cards, wasting gold, pushing decks I didn’t even like later… all of it. This game isn’t like other competitive games where skill alone saves you. Here, card levels hit you in the face. A higher-level card can flip a match you should lose into a win, just because the stats are ridiculous. And hitting Level 15? Yeah, that’s everyone’s dream, but getting enough wild cards and gold, especially if you're free-to-play, is a headache.
So picking the right cards to push first is basically half the battle. I’ve played with almost every deck style, tried different metas, and watched how evolutions have changed things. After all that, I put together this list — but reversed. So instead of counting up to the most important card, we’re starting at 10 and heading toward 1, the absolute must-max card. If you want to speed up your progress with Clash Royale top up, check out LootBar for safe and fast ways to get extra gold and gems.
Each pick includes the Level 15 stats, elixir cost, rarity, and most importantly, why the upgrade is worth it. Let’s get into it.

10. Vines
Vines is one of those cards people overlook until it completely ruins their push. It freezes stuff just long enough to create a window, and it hits both air and ground at the right time. It’s sneaky, but very helpful when you know how to use it.
Why Vines is worth upgrading:
- 3-elixir Epic spell
- Freezes enemies for clean defense
- Helps ground troops deal with airborne threats
- Adds finishing damage on low-HP cards
Level 15 Stats:
- 446 DPS
- 110 tower damage
9. Barbarian Barrel
I’ve always felt Barbarian Barrel is more useful than people admit. For just 2 elixir, you get a wide roll of damage plus a fresh Barbarian that soaks hits or forces a reaction. When you place it at the bridge, the synergy with tower shots is crazy good.
Why Barbarian Barrel deserves Level 15:
- Cheap 2-elixir Epic spell
- Counters Goblin Barrel, Firecracker, Wizard, Musketeer
- Great for cutting down ground spam
- The Barbarian that pops out can deny more value than expected
Level 15 Stats:
- 974 Barbarian HP
- 351 barrel damage
- 279 Barbarian damage
- 214 DPS
8. Cannon
Cannon is the classic “cheap but strong” building. If you play fast decks like 2.6 Hog, you already know how important this building is. It’s not fancy, but it pulls, distracts, stalls, and ultimately saves your tower from being steamrolled.
- Why Cannon is a smart investment:
- 3-elixir Common building
- Great at pulling win-condition pushes
- Cleanly trades into tanks when placed correctly
- Evolution gives a nice boost for heavy pushes
Level 15 Stats:
- 1,197 hitpoints
- 308 damage
- 342 DPS
7. Mega Knight
Everyone hates Mega Knight until they start using him. He’s heavy, but he shuts down spam and punishes overcommitment. If you drop him on a pile of troops, the spawn damage alone clears half the mess.
Why Mega Knight is worth the steep cost:
- 7-elixir Legendary tank
- Jump damage is insane in mid-ladder
- Evolution makes Pekka matchups more manageable
- Can flip momentum instantly
Level 15 Stats:
- 5,808 HP
- 390 area damage
- 229 DPS
- 624 spawn damage
- 781 jump damage
6. Knight
Knight is the definition of “simple but effective.” He tanks, he hits decently, and he buys time for everything else. You don’t get fancy abilities, but you get solid trades almost every time.
Why Knight deserves Level 15:
- 3-elixir Common with great HP-to-cost value
- Outlasts many heavy hitters when supported
- Fits into almost every cycle deck
- Steady DPS that always feels useful
Level 15 Stats:
- 2,566 hitpoints
- 293 damage
- 244 DPS
5. Baby Dragon
Baby Dragon has been good for years and just stays good. Splash from the air is extremely useful, and the fact that it avoids ground targeting makes it survive longer than expected.
Why Baby Dragon is a must-upgrade:
- 4-elixir Epic
- Reliable splash damage
- Synergizes with almost every tank
- Evolution adds a wind effect — speeds allies, slows enemies
Level 15 Stats:
- 1,674 hitpoints
- 234 area damage
- 156 DPS
4. Tesla
Tesla is the building you place when you want control. It hides, it pops up, it avoids spells, and it delivers strong defense. When it’s evolved, the stun effect wipes small troops instantly.
Why Tesla deserves investment:
- 4-elixir Common
- Retracts underground to dodge spells
- Pairs well with almost all archetypes
- Great vs both air and ground
Level 15 Stats:
- 1,674 hitpoints
- 319 damage
- 265 DPS
3. Valkyrie
Valkyrie has been the queen of ground control for a long time. She’s perfect for stopping rushes and controlling crowds. When evolved, her pull-in ability keeps enemies in her spin while hitting air units too.
Why Valkyrie is top-tier:
- 4-elixir Rare
- Shreds swarms effortlessly
- Excellent defensive backbone
- Saves elixir thanks to efficient trades
Level 15 Stats:
- 2,781 hitpoints
- 389 area damage
- 259 DPS
For players looking to fast-track upgrades or get extra resources, a Clash Royale top up on LootBar can help you grab gems and gold safely in the middle of your grinding journey.
2. Arrows
Arrows is one of the simplest cards in the game, but it stays relevant no matter the meta. It clears Firecracker, Minion Horde, Goblin Barrel, and a ton of low-HP troops with zero risk.
Why Arrows is nearly essential:
- 3-elixir Common spell
- Massive area coverage
- Consistent tower chip
- Removes must-kill units instantly
Level 15 Stats:
- 534 area damage
- 135 tower damage
1. The Log
And finally, at the top — even in reversed order — nothing beats The Log. For 2 elixir, it gives control, pushes back enemies, clears swarms, and guarantees value in almost every matchup. If this card is underleveled, you feel it instantly.
Why The Log is the best Level 15 upgrade:
2-elixir Legendary
Clears Skeleton Army, Goblin Gang, Dart Goblin, Princess
Pushback keeps your defenses stable
Works in almost every deck in the game
Level 15 Stats:
387 area damage
59 tower damage
Conclusion:
Upgrading these ten cards to Level 15 will make a huge difference in your overall performance. They’re reliable, strong in multiple metas, and fit into tons of different deck styles. Start from the bottom of this reversed list and work your way up. That’s what helped me climb faster without wasting resources, and it’ll help you too.
