Boros Charm- protects my guys from wrath effects and board wipes. Can be used as extra reach if need be. Double strike can be relevant as pseudo removal.
Deflecting Palm- this one is for boggles, infect and oddly- burn. Works as a functional counter spell in the matchup and can basically be a Lightning Helix. But it's more versatile and used in other matchup a too.
Destructive Revelry- affinity, boggles, twin, bloom, tron, you name it. If it had artifacts, I side it.
Path to Exile- this is for the infect matchup, twin matchup, bloom, instant reanimator, any matchup running big dudes, creature based midrange strategies and frequent combo decks.
Pyroclasm- this one is for a lot of aggro decks. Affinity, burn, soul sisters, certain delver deck (if I see Young Pyromancer and any very quick aggro deck. Not fantastic against merfolk because of the volume of their lords.
Rest in Peace- its for against instant reanimator, living end, vengvine, graveyard decks. There just aren't many around.
Skullcrack- namely soul sisters because that matchup is brutal. But good against boggles and any green decks that might be bringing in Feed the Clan... *shudder*Anyways, please make suggestions. Be it about my mainboard, sideboard, anything. Please ask questions about my choices or even about my meta. Also want to find room for Eidolon of the Great Revel in the 75, it can just be brutal with the explosiveness of BTE, therefore preferably in the SB. It can be a soft lock on some decks and a total lock down on others. Just don't say Tarmogoyf. I don't want to hear it.
