Web-slinging (You may cast this spell for if you also return a tapped creature you control to its owner's hand.)
Pavitr's Sevā — Whenever you cast a creature spell, put a +1/+1 counter on target creature you control. It gains flying until end of turn.
Spider-Man India is a GW counters/aggro commander who turns every creature you cast into a free +1/+1 counter and an evasive flier. You flood the board with cheap, value-laden creatures, snowball counters onto your beaters, and swing through the air for lethal damage. Web-slinging lets you redeploy Spider-Man (or recast him cheaply) to dodge removal and keep the trigger engine online.
Each creature cast grows a creature and grants flying, so you get free evasion and scaling with no extra cards.
Web-slinging makes him cheap to recast and dodges removal by bouncing a tapped attacker back to hand.
GW has access to the best counter-doublers, anthem effects, and efficient go-wide token makers.
Flying is GW's main evasion weakness, and his ability supplies it for the whole team turn after turn.
The trigger only fires on creature spells, so token generators and noncreature spells don't pump.
Each cast pumps only one target, making it slower at true mass go-wide compared to dedicated token decks.
Relies on the commander staying alive to keep the engine running; repeated removal taxes your tempo.
Low interaction in GW means you can struggle against combo and hard control.
