-X/-X spells are especially powerful since you can use them as combat tricks to kill bigger creatures

Master of Ceremonies is a card that always performs

If Sivitris a threat, your opponents will just pay life to kill it, and if theyre not able to deal with it, the +1 doesnt do anything on your way to the other abilities

Of course, this set also sees a brief return to the world of blocks, with the next set being Innistrad: Crimson Vow

Still, you can land it when players have already built out a board or floodgate the number of creatures they can put into play, and if they ever overstep you get to free-role your two best creatures into play

I will, however, remind you, that the card will essentially read "whenever you cast a spell, draw two cards", which does seem quite good
