You play going second with this deck. Here you can do 2 things:
1 summon crimson nova and boost his atack if he is too weak
2 summon link monsters to break the oponents board
The optimal play is to summon crimson nova on the board but this is not always possible. He is very weak against spells and traps and if you are not carefull he's going to get removed from play. He is uneffected by monster effect with an ORIGINAL atack of 3000 or lower. So if your oponent his no set spels or traps summon him and atack for game. He can atack twice if the first atack destroys a monster and in the end fase burn 3000 damage. If you dont have enough atack power boost him with cubic wave or an cubic karma. This is the easiest play and the bread and butter of cubics.
Play number 2 is needed when your oponent has an out to crimson nova you usely do this when the opponent plays an control heavy deck or has a lot of traps set. You want to sent 1 unification of the cubic lord to the graveyard. you can do this with duza or an foolish burial goods. When you draw one use one of your knightmare link monsters to send 1 to the grave if needed. If unification is in the grave it can special summon a cubic monster from the deck or hand when a cubic monster LEAVES the field. Leaving the field happens when you tribute summon or link summon. So get 2 monsters on the field at least 1 cubic monster then link summon a generic link2 banish unification special summon duza and send 1 more unification to grave. Then link summon a link 3 monster activated unification in grave and repeat proces. (Unification is not a once per turn effect).
To play around traps play twin twisters and red reboot. Denko Sekka is also an option but this eats up your normal summon and you cant play there can only be one. This deck also really suffers from handtraps so if this is an problem side deck in called by the graves. Further speedburst dragon can do masive damage and that can easily be an otk but it hurts the consisticy.
