Use usual Orcust strategies with this decklist and play into a DaD on occasionally, when the situation calls for it.
I've removed the two Tsuchinokos for three Apprentice Illusionist Magicians, so it is possible to choose what to discard, granting more secure combo extensions. The A.I.M. alongside D-Hero Malicious, also is a level 6 monster, enabling Krebons to synchro with it fot the newly added Borreload-Savage Dragon.
The one-of Mathematician also is a newcomer to this deck. I was opting for two or three, but I wanted to keep in both, Destrudo and Gizmek Orochi as combo extenders, rather than having more combo starters, as in my opinion, Orcust has enough of them, even Orcustrated Return can be a combo starter under the right circumstances, which are plentiful in this deck.
Curious, the Lightsworn Dominion also can act as a potential combo starter, milling three cards from the top of your deck, each time that a card is added from your deck to your graveyard, and letting you move a card of your choice from your Deck to your Graveyard every turn, without any restrictions on what that card can be.
Barricadeborg Blocker also lets you discard any card each turn, even when you do not have any Continuous- or FIeldspell in your graveyard, as the discard is a cost. The add from graveyard to hand effect will simply not resolve then. As Barricadeborg Blocker also is a Dark Machine Monster, you can summon him in a turn in which you have used Orcust-Crescendo.
Elsewhise, the usual Orcust strategies will work as always.
