This card is stacked, considering it only costs one black and one white mana , oh, and it also comes with sneak, which can be activated for the same cost, guaranteeing combat damage if not countered, and great if you've already got three Ninja creatures on the board
Unfortunately for MTG players, this issue was much larger than just one style of Gala Greeters going missing
Your deck wants to ramp heavily, try adding a balance of early game ramp that costs 2-4 CMC and late game ramp that costs 5+ CMC, some good early ramp options include Farseek , Rampant Growth , Grow from the Ashes , Skyshroud Claim , Circuitous Route , Myriad Landscape , Burgeoning , Blighted Woodland
These cards changed substantially as we iterated on the set, but the core ideas behind both remained intact
