Heading into an overhaul.. Here are some ideas to refine my colour pairs
WU - Blink/Bouncy Castle - less adventure focus
UB - Surveil, graveyard, control
BR - Attacking matters - using reconfigure and menace
RG - Non-human +1/+1 counters
GW - Midrange tokens, populate
BW - stay as lifedrain
UR - Blitz, spells matter
BG - Creatures in graveyard
RW - Boros control
GU - Lands, ramp, elementals theme
