The design for this was based on Mistform Ultimuss ability, and it was later featured on creatures from the Lorwyn block like Shapesharer
Ooooooorrrrr, they may also use the Lum Berry Pokmon Tool card to recover from the state
Pokemon started in 1996 in the first place, so even the card didn't exist in 1995
Terastodon, Woodfall Primus, and Primeval Titan are probably the best cards for the "big green creature" role, but Simic Sky Swallower and Broodmate Dragon can serve the role as well, although they require greater deck manipulation to be able to hard cast should you draw either of them before finding your Natural Order
Theres a fair amount of value in these decks
each wants to turn a big creature into a harder hitting swarm of smaller creatures
