Regarding sideboard answers to creature-centric decks with the Red splash: do people prefer one-shot spells, or permanent/repeatable effects of removal?
e.g.: Sudden Demise, Pyroclasm, Electrickery, Engineered Explosives, Grim Lavamancer, Izzet Staticaster,
Circle of Flame, Sulfur Elemental, etc.
Which card is 'best' largely depends on the current circumstance under consideration, but is there any consensus among players as to which cards are most worthwhile for SB slots? With how popular Young Pyromancer and Monastery Mentor are, I'd imagine that Blade decks would want some additional methods of killing small armies of critters (in addition to Jitte, which will be met with inevitable answers in the postboard games). DnT and Elves are problematic matchups that typically require more than just a handful of StP/LBolt effects.
