It's the Magic: Creep

For those of you who aren't familiar with them, Slivers are a type of creature in Magic who share abilities. Few Slivers don't have abilities. Usually, if you have two slivers on the board, they each have two abilities; one from themselves and one from the other sliver. Add a third sliver and you have three abilities. What kind of abilites? All of them.

Slivers come in all colors, so Flying, Haste, First Strike, Lifelink, Regeneration, Flash, Trample, Shroud, Vigilance, Haste, Double Strike, Protection, Deathtouch, are where they start.

They can be uncounterable, they can work around protection, they can just fuck over permanents,  they can generate mana, deal direct damage, enters-the-battlefield removal, need more slivers? No problem. Card draw? Slivers have it. Sliver-hosing? Yes.

They have keywords that literally haven't been printed yet.

Slivers are crazy.

And in in July, Slivers are back.
