Everyone must play 5c!
Do you choose basics and domain, non-basic fixing to cast Converge and powerful spells, or weaving a narrow path to spells with multiple pips?
My favorite way to play -- 5c Chromatic Madness!
Choose your own adventure of fixing and what they're best for:
Basic land tutoring : Domain
Non-basic Land Fixing : Converge/Sunburst
Filtering for splashes : Splashable Spells
Treasures : Treasure Payoffs
Cheating (Jodah/Fist of Suns) : Big Endgame
Only playing phyrexian mana splashes : More streamlined deck
