Grave Birthing
The Eldrazi Scion is the load-bearing wrinkle here: a plain 1/1 token would just sit on the board, but this one carries a stored colorless mana in its sacrifice ability, so a single instant pays out across three axes at once. You refill the hand with the draw, bank a colorless mana to spend later in the turn (bridging a curve, or edging toward something bigger), and keep a chump blocker or attacker that does not have to stick around to have earned its place. The graveyard exile reads like reach but functions as a soft tax on the opponent: because they choose the card, it rarely lifts the exact one you fear, and it costs nothing to a deck happy to keep filling its own yard. That asymmetry is the whole reason effects like this get printed. What ties the package together is the source: a spell cast from black that produces a colorless creature and colorless mana, black filtering feeding an engine with no color of its own, which is the design signature of this stretch of Eldrazi cards. The instant itself is deliberately modest; the interesting problem it solves is how to stack several small jobs onto one card without any single line demanding you commit to it.
