So this targets a field slot that the Bunny isn't or is on? Wording needs some tweaking.
Seems very weak. Also, what is lava? That's not a real card in game.
If it's free, then you don't need the element sign:
It targets the field slot that the Bunny is on.
Yes, Lava is not a real card in the game, sorry about that.
Just trying to create cards with permanent field changing effects.
The permanent field changing effects can be destroyed by using mass field changing cards
like flooding.
