Decks to Beat
I've spoken with the Sisters of the Flame, who are currently working on a location for a Sunday Old School event. I may have that sorted out for them, but need to speak to Andrew and Paul.
The comments in this thread leave me pleasantly reminded of a meta pre-Brainstorm restriction. I enjoyed then the accessibility of the four Brainstorms to tailor your hands at any point in the game, which allowed you to enact your decks strategy as a function of time (early, mid, late game). The restriction of Brainstorm took away that adaptability decks had. All of the blue decks were relegated to redesign because they had to operate under a condition of more randomness. Cards like Recoup, Tinker-Bot, and even Yawgmoth's Will became liabilities in too many situations to remain the auto-inclusions they once were.
If the comments in this thread are true, then the London mulligan rule should push blue decks slightly back toward their once more interesting history. It should be theoretically more forgiving to play Oath targets or cards like Recoup, because players can put "dead" cards back into the deck, like what was done with Brainstorm. New vintage players tend to overlook the power of Brainstorm because it's not netting any extra cards, but by putting back two useless cards, you are netting two useful cards. (Some people refer to the phenomenon as net virtual advantage). The new mulligan rule essentially has the desired effect of a free turn 1 Brainstorm.
Therefore in the context of virtual advantage, outfitting decks with more "situational" combos, and mitigating mana screw the London mulligan rule should have a positive effect on Vintage, specifically on the limitations of blue/combo deck construction. (Also a natural predator of Dredge decks)
@stuart I play 2 Karakas, they may help protecting Kataki (I must have it in play and untapped, though). I also play Suppression Field, so activating Ballista should cost them 2 mana. And I'll try Tabernacle too, so the idea will be that they will have to pay for too many costs to do their thing.
@blindtherapy It's not my list, and probably just a test list, but I feel this can be something. Those 4 Lotuses
