Mind Swap — You may have Superior Spider-Man enter as a copy of any creature card in a graveyard, except his name is Superior Spider-Man and he's a 4/4 Spider Human Hero in addition to his other types. When you do, exile that card.

Web-slinging W (You may cast this spell for W if you also return a tapped creature you control to its owner's hand.) As Arachne enters, look at an opponent's hand, then choose a card type other than creature. Spells of the chosen type cost 1 more to cast.

Web-slinging RG (You may cast this spell for RG if you also return a tapped creature you control to its owner's hand.) Trample Sensational Save — If Scarlet Spider was cast using web-slinging, he enters with X +1/+1 counters on him, where X is the mana value of the returned creature.

Deathtouch, lifelink Whenever Gwenom attacks, until end of turn, you may look at the top card of your library any time and you may play cards from the top of your library. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.
