How it works
Cast Body of Research by paying , creating a 0/0 Fractal creature token, then putting a number of +1/+1 counters on it equal to your deck size.
Cast Bioshift by paying G/U, moving all +1/+1 counters from the Fractal onto Hallar.
The Fractal dies as a state-based action due to having zero toughness.
Cast any kicker or multikicker spell with kicker by paying its mana cost plus its kicker cost.
Hallar triggers, putting a +1/+1 counter on itself, then dealing damage equal to the number of +1/+1 counters on it to each opponent.
This potent combination starts by resolving a massive Body of Research, which floods your board with a Fractal creature token loaded with a mountain of +1/+1 counters equal to your entire library. You then use Bioshift to cleanly transfer that staggering hoard of counters directly onto Hallar, the Firefletcher, scaling its power to astronomical heights in a single swoop. With Hallar now sitting on a colossal number of +1/+1 counters, simply casting any kicked spell triggers Hallar's ability to unleash fatal damage to each opponent.
