Lightning and Poison: The Short Version
Lightning is a big hit on a few strong targets. Poison is a slow area burn. Pick the one that matches your deck.
Lightning costs 6 elixir. RoyaleTracker’s card notes say it damages and stuns up to three enemy troops, with reduced damage to towers. Poison costs 4 and damages everything in an area for a few seconds. They are both big spells, but they solve different problems.
Why it matters: a beatdown deck needs to break a building fast. A control deck needs to punish swarms. The right spell makes your deck work.
Cause and effect: Lightning costs 6, so you need an elixir lead to play it. Poison costs 4, so you can play it earlier. A cheaper spell means an earlier play and more chances to use it.
Spells are often tuned in small steps. If one gets cheaper or stronger, deck lists will switch quickly. The negative effect: players who commit Gold to a deck built around one spell can see their plans change after a single balance note.
Best Lightning Decks in October 2026
| Deck | Style | Avg elixir | Needs |
| Electro Giant, Evo Baby Dragon, Hero Bowler | Beatdown | 4.4 | 70.6% (657 battles) |
| Goblinstein cycle with Evo Archers and Evo Skeletons | Cycle | 3.3 | 69.8% (895 battles) |
| Evo Witch and Evo Skeleton Army with Elixir Golem | Midrange | 3.8 | 65.5% (983 battles) |
| Royal Hogs with Evo Archers | Siege-cycle | 3.4 | 60.2% (762 battles) |
The pattern is clear: Lightning appears in both heavy and cheap decks, and the top Electro Giant list pairs it with Tornado and Barbarian Barrel. For the heavy build, read our Electro Giant guide.
Quick math: Lightning costs 6 and Poison costs 4, a gap of 2 elixir. Two elixir buys Skeletons plus Ice Spirit, so the spell you pick decides what else you can play.
Best Poison Decks in October 2026
| Deck | Cards | Avg elixir | Needs |
| Evo Cannon and Evo Bats cycle | 2.9 | 70.1% (3,000 battles) | |
| Graveyard Poison, Evo Baby Dragon, Evo Knight, Hero Ice Wizard | 3.4 | 64.6% (1,300 battles) | |
| Graveyard Poison, Evo Baby Dragon, Evo Knight, Hero Tombstone | 3.4 | 64.0% (1,300 battles) | |
| Evo Baby Dragon, Hero Ice Wizard, Hero Tombstone, Knight | 3.4 | 62.5% (1,700 battles) |
RoyaleTracker says Poison pairs most often with Ice Wizard, Tornado, Barbarian Barrel and Graveyard. That is the Splashyard family, which has its own page: the Splashyard guide.
Poison is tied to the Splashyard family today, and Lightning to Electro Giant. If one of those decks falls out of favor, its spell falls with it. The negative effect: players who build around one spell can lose a whole list when its host deck is nerfed, so it pays to learn how the other spell plays.
The facts: both spells have decks above 60%. What it means: the spell is not the point; the deck around it is. Still unknown: how the ranking moves after the next balance patch.
| Build | Cards | Avg elixir | Needs |
| Lightning cycle deck (Evo Archers and Evo Skeletons) | 3.3 | 69.5% (853 battles) |
Try it yourself: open the Clash Royale Deck Builder with a Lightning deck from the tracker, 69.5% in the tracker sample (853 battles), already loaded. Swap Lightning for Poison to compare the cost side by side.
How to Choose Between Lightning and Poison
- Choose Lightning if your deck has a heavy tank and needs to break a building or a cluster of troops fast.
- Choose Poison if your deck plays defense first and wants to punish swarms or support a Graveyard.
- Check your elixir: Lightning costs 6, so it needs a deck that can afford it.
- Check your enemy: Lightning is better against buildings and heavy troops, Poison against clusters.
Rule of thumb: if your plan is one huge push, take Lightning. If your plan is to hold the lead and chip with Graveyard or a cycle, take Poison. Both together cost 10 elixir.
The move: pick the spell that matches your win condition. Heavy tank, Lightning. Graveyard or control, Poison.
If special upgrades keep boosting spells, both could get more variants. The negative effect: more variants means more complexity for players, and a spell that was a simple choice could become a puzzle of timing and slots.
For spell basics, read why you should use the Lightning spell and the ultimate guide to using Poison. The slot rules are in the deck slots guide.
Here’s the problem: a six-elixir spell that hits nothing is a lost game. Wait for the right targets.
