Whenever you gain life, put a +1/+1 counter on Trelasarra and scry 1. (Look at the top card of your library. You may put that card on the bottom.)
Trelasarra turns every lifegain trigger into a +1/+1 counter plus a scry, so you build a critical mass of cheap, repeatable lifegain effects and beat down with a snowballing commander. Early turns ramp and deploy lifelinkers or incidental lifegain enablers; mid-game your scry trigger smooths draws while Trelasarra grows into a one- or two-shot kill. Suit her up with protection and trample to close fast.
Extremely cheap commander (2 mana) that grows for free off effects you'd already run
Built-in card selection via repeated scry keeps draws consistent
GW has deep, efficient lifegain and counter-synergy support
Can win through combat as Voltron or pivot to go-wide lifegain payoffs
Heavily commander-dependent; removal on Trelasarra stalls the whole plan
Lifegain alone doesn't close games—needs evasion or a payoff to convert
Vulnerable to board wipes and counter-removal effects
GW lacks strong interaction, card draw, and combo resilience compared to other color pairs
