I'm really tempted to make a Gisela aggro deck for EDH with lots of land destruction and board wipes. Use artifact ramp to get Gisela, drop an Armageddon. Maybe suspend a Detritivore or Greater Gargadon or Benalish Commander first to enable Obliterate or Decree of Annihilation! That sounds like fun, right? Oh man maybe I could even play Storm Cauldron. How sweet would that be.

And of course there are instant wins. If I can give Gisela +1/+0 and Double Strike, she can one-hit. SO Savage Beating, True Conviction, Sunhome, Fireshrieker seem good. Ooh, and Avatar of Slaughter! Yes! With multiple ways to grant double strike, equipment like Loxodon Warhammer or Swords become attractive. Also, Malignus and Heartless Hidetsugu can both one-shot--Malignus one guy at a time, Hidetsugu the whole table. Mana-Charged Dragon is potentially good--trample and firebreathing seem nice. And Taurean Mauler seems quite good as just a random big dude.

So tempting. So very tempting.
