The Crimson Queens

Convoke, Partner, Royal Court (Creatures with
Royal Court get +1/+1 for each other creature on
the battlefield with Royal Court.)
Creatures you control are red and white in
addition to their other colors.
When The Crimson Queens attacks, other
attacking creatures you control gain first strike
until end of turn if a Legendary creature you
control has first strike. The same is true for fear,
double strike, landwalk, protection, trample, and vigilance.
