Just use the art sleeves and an oversize sleeve to double-sleeve slightly differently
That could happen any number of times you can muster, rather than just once per attack as is the case with Sword of the Animist
Personally, outside of these, look out for Vivi ornitier or some of the rarer Chocobo colours too, including the black one in Japanese texttheyre some of my favorites from the set
Tutors, fast mana, and infinite combos are rarer in this tier, but most decks will still have at least one combo and a few tutors
Use the mana value of the creature as it last existed on the battlefield to determine the value of X
Even attached to a weak body, this is a great combo piece that can do silly things, especially if you can give it haste
