Ulut, Spectral Swarm

Companion — Your starting deck contains only
land cards and exactly four copies of each
nonland card.(If this card is your chosen companion,
you may put it into your hand from outside the game
for {3} any time you could cast a sorcery.)
Whenever you cast a spell, if you spent mana to
cast it, spells with that name cost {1} less to cast
until end of turn. Then, if you've cast a spell
with that name this turn, draw a card.
