Arcane Barrier 1 (If you would be dealt arcane damage, you may pay {r} to prevent 1 of that damage.)
Spellvoid 1 (If you would be dealt arcane damage, you may destroy this to prevent 1 of that damage.)
At the beginning of your action phase, destroy this.
When this leaves the arena, deal 1 arcane damage to any target. If damage is dealt this way, amp 1. (The next time you would deal arcane damage this turn, instead deal that much plus 1.)
Viserai Specialization (You may only have this in your deck if your hero is Viserai.)
Create X Runechant tokens.
If X is 6 or greater, target hero discards 3 random cards.
If you have a base arms equipped, transform it and X Hyper Drivers you control into this, then equip this. If you do, the next time you would be dealt damage this turn, prevent twice X of that damage. (Put the transformed cards under this in your arms zone.)
Whenever you boost an attack action card, you may destroy a card under this. If you do, the attack gets +2{p}.
