Secret Lair Drop

This creature enters with X +1/+1 counters on it. At the beginning of your upkeep, double the number of +1/+1 counters on this creature. This creature has trample as long as it has ten or more +1/+1 counters on it.

Whenever a permanent an opponent controls is put into a graveyard, put that card onto the battlefield under your control unless that opponent pays 3 life.

Creatures can't attack you unless their controller pays 2 for each creature they control that's attacking you.

When this creature enters, create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.") Whenever another creature you control enters, you gain 1 life.

All Sliver creatures have "T: This creature deals 2 damage to any target and 3 damage to itself."

At the beginning of your upkeep, you may exchange control of target nonland permanent you control and target nonland permanent an opponent controls with equal or lesser mana value.

All Sliver creatures have flying. All Slivers have "If this permanent would be put into a graveyard, you may put it on top of its owner's library instead."

Indestructible As long as your devotion to red is less than five, Purphoros isn't a creature. Whenever another creature you control enters, Purphoros deals 2 damage to each opponent. 2R: Creatures you control get +1/+0 until end of turn.
