Why not put Yubel - Terror Incarnate x3 as well since you put x3 for all the other forms.

fires of doomsday would be great for yubel here

most deck are base on controling their own field to win, but if the main point of this is Yubel, you need to have monsters on your opponent field....

add some nightmare demons.

and calculator for instant 3k beatstick

i think yubel is strong enough for a potential kill or control

Thanks for the suggestions .
@titration
yea i have fires of doomsday in my side deck cause basically this deck's aim is to throw cards into the graveyard with dark grepher and armageddon knight and special summoning them. (therefore not in the main one)

@RedEyesFan
i didnt know that the card nightmare archfiends existed thanks for sharing (think i might use them)
however, calculator is kinda dangerous imo if my opponent used magic cylinder D: it would be a slap to my face

play 3x montage dragon and 3x calculator . . .

you can try scapegoat
