Perhaps this is a familiar story to you- You are playing a one on one EDH game, your opponent is a Glissa the Traitor combo deck.  Turn two drop for Glissa- executioner's pod.  Oi vey, that card is free recursion for Glissa as long as I have creatures, and as I play mono-green I have a lot of those.  Turn five Glissa pops a demonic tutor.  Turn six, Mindslaver.  We kept playing because the round of our draft hadn't started but I had lost as soon as the 'slaver hit the table, and presumably even when he cast the tutor.  The coup de grace- I had Kamahl in hand when Mindslaver resolved, providing my opponent with as many Mindslaver recursions as I had LANDS.
