the current top-50 has more farms, more speed and some stall, but winning without any shield is possible
most decks only pack 1 or 2 shield, in that case, when they cant draw them in first 5 or 6 turns, they lose
this deck win consistnetly in 5-6 turns, time mostly depends on which quanta does the first turn quantum pillar gives, when it gives 2 entropy, with a supernova or two, no fire rush can beat you

another variations are mostly about time, you can sub precognitions with 2 quantum plus 2 fate eggs or 2 quantum plus 2 hourglasses
this deck has no problems against SoG, Sod or miracles, cause you can easily pack 40+ damage in 4-5 turns, and it gets higher with right creatures or Lava Destroyer+Forest Spirit
the logic behind frog, cocatrice and spirit is: you will need that second growing creature, frog is just good, and you need at least some creatures against rof
5 quantum pillar is the right amount with the auto mulligan, i think
the cards and the concept is really common but i just want to share my opinion about the speedbow and current t50
happy grinding
