Don, the Sleepy Khan

Don, the Sleepy Khan's power is equal to the number of lands on the battlefield.
Don enters the battlefield tapped and can’t block.
At the beginning of your upkeep, if Don is untapped, tap it.
When Don enters the battlefield, you may search your library and/or graveyard for a card named As Clear As Day and attach it to him. If you search
your library this way, shuffle.

"His ignorance is so profound it bends reality."
