Here is the solution to yesterday's Magic: The Puzzling, "Double Duty." The steps can be performed in a slightly different order, but the general idea is as follows:
- Tap the plains and two islands to add to your mana pool. One island is destroyed by Blight, but that doesn't matter.
- Play Green Ward on Paul's Bog Imp. Both Webs fall off the Imp.
- Play Enchantment Alteration on the Green Ward. Move it to your War Mammoth.
- Play Unstable Mutation on the Mammoth.
- Attack with the 6/6 War Mammoth. Because it has protection from green, it can not be blocked by the Grizzly Bears or the Giant Spider. Paul can block with the Bog Imp, but even if he does, you can assign five trample damage to Paul, killing him.
