Proccing Goblin Bombs isn’t enough value, however because your opponent is disincentivized to destroy them, using them as buff targets seems to be a sneaky and viable strategy.
The goal is to have enough bombs generated to reliably have a token to buff on the board.
When lethal is near, play Nechromechanic along with small buffs (Dire Wolf, Fireworks Tech, Sun Cleric, Spider Bomb, Argus) or token destroyers (Goblin Prank, Void Ripper, Abomination) to burst your enemy down.
