(MY english is no good sorry) This is the version than I use, normaly i I got 7900 (No damgae in my LP), use a prismatic card to get 8100, my prismatic is enemy controler (replacing 1 Ready for intercept). I use 2 Union attack but if you have only one you can use a Spell Reclamation, and my Extra Deck have BEUD
last turn order:
1. Use Summoner of Illusions and sacrifice Unhappy girl to Summon BEUD (You need to set SoI only when you have 1 card left in your deck)
2. Summon Relinquished using SoI as sacrifice.
3. Summon Gravekeeper Vassal and use Murmur of the Forest to remove Necrovalley
4. Use Union Attack and Secret Pass to the Treasures on Gravekeeper Vassal, and last use Relenquished
Just finished using this. It's extremely consistent. Messed up the first time due to user error: I wanted to free up a S/T zone on the last turn and chained Ready For Interception into Murmur of the Forest. Stupid mistake that others could learn from.
