Useful in an Exxod Burn deck. If you have "Stumbling" on the field, "Exxod Master of the Guard", and any flip summon effect rock monster, like "Golem Sentry" as well, its will chain as follows. Exxod's effect, Stumbling, Rock monster's flip summon effect. This gives the 3 chains neccesary to add "Accumulated Fortune" on as the 4th chain.
This card fits perfectly in a Chain Burn/Chain Strike OTK deck, as the Deck is capable of creating long Chains with different card names to fulfill this card's activation requirement. In addition, this card's draw effect is strongly appreciated by the Deck as it tends to use up its hand very quickly.
