Youre incentivized to have a large chunk of basics for Mitotic Manipulation, and as a 2-color deck, you dont need a ton of other fixing lands
You can easily get for 3+ damage in most white builds, which is quite efficient (do try to avoid trading early though, as it can hurt you later)
It gives you more casts for the Reservoir gameplan and with the grim monolith + helm ramp, Mox Emerald, and Eternal Witness, it completely locks the game out with a recursive loop
Discounting the ones that are banned in Historic (which I don't really care about), I have 28 of the 48, which adds up to a 58.4% completion rate
