Why would you use Union Attack + Vassal instead of Gift of the Martyr and Piranha Army? You only need one GotM rather than 2 union or 1 + spell reclamation? I get that PA wasn't available for a while but neither was US. Other than for the effect damage mission, it makes no sense to me
Here's my version of the dino deck. 100% consistent win rate.
Note : i don't have twister or a 3rd de-spell so i use treaty on uniform trap card. also, if you have 2 ritual weapon. replace rising energy with a 2nd one or vice versa.
1. Tribute summon blue eyes
2. Fusion summon bracchio
3. Ritual Summon Cu chu
4. Secret pass to treasure > cu chu
5. Riryoku blue eyes > Cu chu
6. Gift of martyr > blue eyes > Cu chu
7. Activate Cu chu effect > Blue eyes
8. Equips/Rising energy > Cu chu
9. Let Cu chu grape mako in the arse
The Cerberus deck works as well for 10000 damage. Mako only has magic cards which he will not activate with Cerberus on the field. I have not had an issue with bugroth attacking directly.
