Roon is a Bant blink engine: each turn you tap Roon to flicker a creature, re-triggering enter-the-battlefield effects to generate value, ramp, card advantage, and removal via tempo. You grind incremental advantage, snowball a board of ETB value creatures, then convert that into a lethal swing or a combo finish.
Tighten the curve with cheap, high-impact ETB creatures and fast ramp (Sol Ring, Cultivate, Smothering Tithe) so Roon comes down protected and active early. Add a compact combo line like Deadeye Navigator + Peregrine Drake/Palinchron with Craterhoof or a Walking Ballista mana sink, plus protection like Heroic Intervention and Swiftfoot Boots. Trim purely durdly ETB cards for efficient interaction (Cyclonic Rift, Swords to Plowshares) and flicker-flexible threats like Agent of Treachery.
