The Wayward Sorcerer might not be the most playable card on this list, requiring you to build around Broom cards, but it still demands a high value given its Enchanted status and beautiful alternate artwork
The drawback is that you can also turn into the target of the whole table
If an opponent creature is reduced to 0 toughness through his ETB (Enter the Battlefield) effect, they'll die, adding another +1/+1 counter to Sephiroth
It wasnt the most powerful set mechanically, but it's hard to find an expansion that tops War of the Spark story-wise
Its built around a simple but powerful theme of putting +1/+1 counters on your creatures
Its good later on in the game when you have bad cards, but I want to be drawing cards early and throwing threats down later, so Tormenting Voice does not make the cut
