Now let's turn to these two Black cheap cost enchantments
W for a 1/1 (So far, so good.) 2W for a 2/2 (Pearled Unicorn, but not horrible.) 10W for a 5/5 first strike creature (Wait, what?) 1U for a 0/3 (Eh, but bearable.) 3U for a 0/6 (Getting pretty bad here.) 11U for a 6/6 islandwalk creature (Wait, what?) B for a 1/1 (Muck Rats, but okay.) 4B for a 3/3 (Looking a little worse here.) 12B for a 5/5 creature with pseudo-fear (Wait, what?) Those ultimate mana costs were paid out over multiple turns, but if your creature died before hitting their highest level game over, tons of wasted mana, yikes
