Vannifar is a four-mana green and blue 3/4 that allows you to do this for free at the beginning of combat on your turn, or you can put a +1/+1 counter on each colourless creature you control

Aboshan dies easily for a six mana creature - that three toughness is below the threshold for red commons in the draft (Fiery Temper, Firebolt with flashback, Flame Burst with another Burst or Pardic Firecat in the yard, Acceptable Losses, Swirling Sandstorm, Kamahl's Sledge, Sonic Seizure, and Ember Shot will kill it), making it a little too fragile to survive in most instances
As well as a basic land, this card could be a guild gate, a signet, or something more exciting
Showcase Soft Glow cards can be found in some Draft, Set and Collector Boosters
