Feline Ferocity is the Cat deck
With the Temple cycle and Triomes leaving in the fall, well only have access to five true come into play untapped duals in the Snarl cycle
Aside from that, I think there are better spells you can run at the four-mana spot in your red decks
While mana intensive, the ability to repeatedly refute an opponent's turn by bouncing their guy combined with the ability to use Disappear as a way to "protect" your creatures in combat (cast Disappear on it and then attack freely, knowing you can save it from lethal damage) made for a very potent enchantment that acted more as a sorcery than an enchantment
There are many different ways in which these characters can appear, but the one that we see here is seen in Ruby, Sapphire , and Emerald games
Both serve similar functions
