"Performapal" was one of the most consistent decks of all time , as its pendulum monsters, which are both monsters and spell cards, dominated the meta for a few weeks before being heavily nerfed by the banned list
Like most Pokmon cards, the value of Flaaffy depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Unseen Forces)
Solid metal novelty cards make up the third category
:'c *hint: look in the background, just like Cubone's* These are so sad
Lastly, using Cloudstone CurioCloudstone Curio to return a Summon to hand that has a finality counter on it is another way around the exile effect
This is decent against 1/1 thopters and 2/2 zombies but there are increasingly 4/4 tokens kicking around, direct copy token too, all of which stand to make this a fairly good value removal spell
