Thwip!

When Anti-Venom enters, if he was cast, return target creature card from your graveyard to the battlefield. If damage would be dealt to Anti-Venom, prevent that damage and put that many +1/+1 counters on him.

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.

Whenever another creature you control enters, you gain 1 life. If it's a Spider, put a +1/+1 counter on it.

Flying When this creature leaves the battlefield, create a Food token. (It's an artifact with "2, T, Sacrifice this token: You gain 3 life.")

This artifact enters with two +1/+1 counters on it. T: Move a +1/+1 counter from this artifact onto target creature you control. Activate only as a sorcery. Whenever a modified creature you control leaves the battlefield, put a +1/+1 counter on this artifact. (Equipment, Auras you control, and counters are modifications.)

When this creature enters, choose one — • Puff Piece — Put a +1/+1 counter on each of up to two target creatures. • Investigative Journalism — Return target creature card with mana value 2 or less from your graveyard to your hand.

Flash When Flash Thompson enters, choose one or both — • Heckle — Tap target creature. • Hero Worship — Untap target creature.

Enchant land When this Aura enters, create three 1/1 green and white Human Citizen creature tokens. Enchanted land has "1, T: Target creature gets +1/+1 until end of turn for each creature you control. Activate only as a sorcery."
