Legendary Creature - Spider Hero Symbiote Scarlet Spider, Ben Reilly Web-slinging (You may cast this spell for 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
While providing your opponents with mana sources comparable to treasures may seem counter-intuitive, whenever an artifact an opponent controls is put into a graveyard (such as when they sacrifice a Banana), each Ape and Monkey you control gains a +1/+1 counter, meaning your opponents' treasures can cause your creatures to grow to massive sizes
It's priced at $49.99 and ships free like every other order
