i would like to see something like this or JimmyMethod's concept with same card name for Nature, maybe not so brutal (not replacing whole hand)... similar like Beast master maybe
replace lowest rarity non-Nature card in opponent hand with common Nature
wall: +4N
N = #Nature in hand
oponnent wall: -4M
M = #Nature in opponent's hand
Replace a card in hand with self (persistent but not Durable, to avoid replacing it with rare Nature when triggering Nature)
