Yes, you can do a lot more with this deck; first off, this should be all about hand control and limiting options, so here's something I'd try out...
18/
1 Dark Armed Dragon
1 Chaos Sorcerer
1 Cyber Dragon
2 Thestalos the Firestorm Monarch
2 Zaborg the Thunder Monarch
2 Mystic Tomato
1 Sangan
1 Spirit Reaper
3 Necro Gardna
2 Don Zaloog
2 DD Assailant
14/
1 Heavy Storm
1 Mystical Space Typhoon
1 Monster Reborn
1 Brain Control
1 Reinforcement of the Army
1 Soul Exchange
1 Smashing Ground
1 Fissure
1 Giant Trunade
3 Shrink
2 Book of Moon
10/
3 Solemn Judgment
2 Bottomless Trap Hole
2 Phoenix Wing Wind Blast
3 Mirror Wall
42 total ; more total is so that you don't draw into multiple tomatos or draw into all your rota targets before drawing rota.. stuff like that.
Necro Gardna is win with tomato... and good with PWWB.. which is good for limiting options.
