Look at target hero's hand and arsenal. At the beginning of their next end phase, they discard all cards in their hand and destroy all cards in their arsenal.
Search your deck for up to 3 traps, reveal them, put them into your hand, then shuffle 2 cards from your hand into your deck.
This card's {d} is equal to the number of equipment you control with Arcanite in their name.
Spellvoid X, where X is the number of equipment you control with Arcanite in their name.
Guardwell (When the combat chain closes, if this defended, put -1{d} counters on it equal to its {d}.)
The next time an attack you control hits a hero this turn, deal 4 arcane damage to them.
Go again
Meld (You may play 1 or both halves of this card. Each costs 0.)
Deal 1 arcane damage to any target.
Return an attack action card with cost less than X from your graveyard to your hand, where X is the total arcane damage you've
dealt to opposing heroes this turn.
Go again
Legendary (You may only have 1 Will of Arcana in your deck.)
When this is pitched, amp 1. (The next time you would deal arcane damage this turn, instead deal that much plus 1.)
(Defense reactions can be played from hand or arsenal to defend.)
Decompose - You may banish 2 Earth cards and an action card from your graveyard. If you do, this gets +1{d}.
Deal X+3 arcane damage to target hero, where X is the number of aura permanents you control with Sigil in their name.
Surge - If this deals more than 3 damage, gain 1{g}, then shuffle all aura permanents you control with Sigil in their name into their owner's deck.
Your next Runeblade attack this turn gets +1{p}.
You may destroy an aura you control. If you do, each opponent destroys an aura permanent they control.
Go again
Arcane Shelter 1 (If you would be dealt arcane damage, destroy this to prevent 1 of that damage.)
When this leaves the arena, create an Embodiment of Lightning token.
