The Knowstorm

This can be your commander.
Whenever you draw cards, put a time counter on The Knowstorm.
If there are 1 or 2 time counters on The Knowstorm,
look at the top 2 cards of you library. Put any number into your hand. If there are 3 or more time counters on The Knowstorm, creatures you control gain Mindbend until end of turn. (Whenever this deals damage to a player, they
draw that many cards and then discard that many cards randomly.) Then, transform The Knowstorm into
Borun, the Storm's Apex.
