Play as Sentinel and build Sacred Rage against Dynamo.

Deploy your robot Sentinel to shut down Dynamo's electric trap! Hitting Dynamo directly will only damage your own bot, as his shield reflects your attacks and drains your special meter. Sentinel provides the ultimate counter. Hold your block against his shocks to build up massive critical hit damage, then unleash your counterattack to shatter his power grid. Take down the arena boss to earn rare Sentinel Transform Cards and evolve your robot into an unbeatable guardian!
