cyber jungle booster box Yu-Gi-Oh! TCG: Cyberstorm Access : Toys & Games and Iron Leaves makes their debut as Pokémon ex Pokemon Booster Boxes - Collector's

Its a cool card to play in decks that use proliferation, counters, and even tokens, considering that sometimes just placing a +1/+1 counter on everybody is worth a card

Also a 2 colorless energy retreat cost is pretty cheap for a powerful stage 2 Pokemon like this one and good thing it doesn't take up too much energy since you'll want to retreat it if you are getting close to feinting since ex cards let your opponent take 2 prize cards once they are knocked out, but feinting shouldn't be too much of a problem with this card because of its high hp and a two type resistance

If not, why not

The 7 mana worries me less since black has things like Dark Ritual, Cabal Coffers, and Crypt Ghast in it's arsenal
