Hearthpwn

It's like Rattlegore.

There's a bunch of hidden versions of the card that each do one more damage than the previous one.

Think of them as ranks.

So rank 1 does 2 damage, rank 2 does 3, rank 3 does 4, etc.

The hidden text is effectively...

Ignite [Rank 1]
Deal 2 damage. Add an Ignite [Rank 3] to your deck.

Ignite [Rank 2]
Deal 3 damage. Add an Ignite [Rank 3] to your deck.

Ignite [Rank 3]
Deal 4 damage. Add an Ignite [Rank 4] to your deck.
