My plan at GenCon against Gifts was
-Rack and Ruin
-Goblin Welder
- Pentavus
-Fire / Ice
- Mana Drain
- Echoing Truth
+3 REB
+ 2 Crypt
+ 1 shaman
Thanks for the suggestions! I just have a few questions as I don't fully understand your choices. Why sideboard out the Pentavus over Triskelion? Pentavus is bigger and allows for the slave lock (even though a lock is not always neceassry to secure the win) and they don't have any little men to shoot with the trike. Secondly, why did the Echoing Truth come out? I though bounce was one of the best ways to deal with a Darksteel Colossus once he's in play if there are no artifiacts in your opponents graveyard.
