There are options to use it more times. Though, it's kinda dependant on stuff in hand, I think.

I think the key to looping it an additional time would be Xtra HERO Cross Crusader, but it's tricky finding the right way to do it.

Like, you could use Fusion Destiny on a Denier and Malicious in the deck, to summon one of several fusions (Destiny HERO Dangerous, Dystopia, Dusktopia, Destroy Phoenix Enforcer...). Then, if you have a third D-HERO in the GY (you could make it happen with Dangerous; dump Dynatag, probably), you could summon Malicious and Denier with their own effects, and then have Denier set the banished Malicious on top of the deck.

But from there, immediately summoning Cross Crusader wouldn't be the best idea; you could revive Denier, but he wouldn't have a banished Malicious to recycle yet, since you have to use Cross Crusader's revival effect as soon as he's summoned.

Maybe if you have Mask Change in hand. You could use it on Malicious to summon Masked HERO Dark Law (always a fun thing to do), then banish him to summon the one that Denier recycled earlier. Then, link Denier and Malicious into Xtra HERO Cross Crusader, and revive Denier to recycle the banished Malicious into the deck. Then, you could banish Malicious again to summon one more Malicious.

Granted, from there, I'm not sure what you would want to do from there. You're locked into Dark HERO monsters for the turn...

Maybe you add another Denier to the hand by tributing Denier with Cross Crusader, then link Cross Crusader and Malicious into Xtra HERO Dread Decimator. Normal summon the Denier you added to the hand, put your banished Malicious on top of the deck, and then banish the Malicious you linked away, to summon another Malicious?

So, assuming you summoned Dangerous initially, that's like 9000 damage on board, with the opportunity for more if you have Dynatag in the GY. You could also link the last Malicious and Denier away to summon Xtra HERO Infernal Devicer, if you have monsters listed as fusion materials to grab from the deck.

It's not the most consistent thing in the world, but there's definitely potential for Denier to do some silly stuff with Malicious.
