My machine gun gadget deck rate and advice please?

[RyanMichaud]

3 Catapult Turtle
3 Red Gadget
3 Yellow Gadget
3 Green Gadget
1 Scrap Recycler
1 Cannon Soldier MK21? I think is it's name
1 Sangan
3 cyber Dragon

3 ultimate Offering
3 Pot Of Avarice
3 Dark Room Of Nighmare
2 MST
2 Nobleman Of Crossout
2 Magic Cylinder
1 Cease Fire

1 Card Destruction
2 Magical mallet
2 Dark Bribe
1 level limit area b
1 Messenger of Peace
The point of the deck is to bring out catapult turtle while ultimate offering is out and keep summoning gadgets and repeat.
I chose the catapult turtle instead of Cannon soldier mk21 because for each monster I tribute I inflict 300 damage while every 2 monster I do 300 with cannon soldier. Please rate and give advice.
