Festergloom: limited needs this Fleshbag Marauder: a solid card in all formats, especially ones with lots of creatures
If you are jamming a few Eldrazi Titans and don't want to wait ten turns to cast them, you can power them out on turn six or so with the right ramp package
Its low mana cost means that any deck along the aggressive to control spectrum can play it, and since its colorless, you can slot it in anywhere and cast it using any color
I'll admit I was a bit skeptical at first, but in early design we always try things because sometimes, as was the case with DFCs, what seems dubious ends up playing well
Aside from the top cards, Fates Collide has a solid supporting cast, but not enough to catapult it into the top-tier of X&Y sets, as some of the best X&Y booster boxes are packed with popular Pokemon
Getting three or four spiders each time you cast the card isnt hard, and its a must in spider typal decks
