beholder cards mtg If you cant MTG Secret Lair: Death is

The number of counters on it and the number of cards in your hand are only checked when that ability resolves

(10/1/2008) The number of Saproling tokens created by the triggered ability is based on the number of +1/+1 counters on Mycoloth, not on the number of creatures Mycoloth devoured

It rewards smart sacrificing and moving of counters, and has some fairly large creatures of its own to allow you to enact your gameplan with minimal interruptions

Paying 3 mana for it is already a fine rate

Among recent MTG black cards, few close games this cleanly without committing to combat

Instead, it gives Prosper's controller an extra impulsive draw each turn
