Solemn Spirit

Whenever a time counter is removed from a suspended card with crawlback, you may draw a
card or create two 1/1 blue spirit creature
tokens with flying.
As long as Solemn Spirit is suspended, creatures
you control have hexproof and deathtouch.
Exile Solemn Spirit from your graveyard:
Suspend it with 2 time counters on it. It gains crawlback 2.
