The Cursed Eye of the Dragshift Revenger has bad consistency

My old Luard deck kept losing

So I'd thought I'd go back to basics with a deck I've won once or twice with in the past, my good old Diablos, but I'll inject some life into the deck using the TD-10.

So far, I've decided this line up:

Grade 4 (9)
4x Dark Dragon, Phantom Blaster "Diablo"
2x Dark Dragon, Carnivore Dragon
2x Dark Knight, Grim Recruiter
1x Supremacy Black Dragon, Aurageyser Dragon

Grade 3 (7)
4x Blaster Dark "Diablo"
2x Dragheart, Luard
1x Deathspray Dragon

Grade 2 (11)
4x Bloodstained Battle Knight, Dorint
4x Dark Night Maiden, Macha
2x Dragwizard, Liafail
1x Dark Saga Painter

Grade 1 (15)
Currently working in progress, testing
4x Arduous Battle Knight, Claudus
3x Dragwizard, Knies
2x Dark Heart Trumpeter
1x Pitch Black Sage, Charon
1x Night Sky Eagle
4x Little Skull Witch, Nemain

Grade 0 (17)
1x Promising Knight, David
Considering the 8/4/4 (crit, draw, heal) or the 3/6/3/4 (crit, draw, stand, heal) or the 8/3/1/4 (crit, stand, draw, heal) or rainbow, but for memes sake and because I like big hands, I'm going 11 Draws...
4x Howl Owl
4x Freezing Revenger
2x Dragprentice, Miach
1x Tactician of Godly-calculations, Orphe
1x Cursed Eye Raven
4x Flatbau

Let's see how well an OG deck with minor edits does...
