Riku the Many

At the beginning of your upkeep draw half X
cards, add half X mana of any color to your
mana pool, and up to half X target creatures
get +X/+0 until end of turn where X is the
number of creatures you control named Riku
the Many. (This mana does not empty from
your mana pool as steps and phases end)

until the end of your next turn
