Well I just did 10 games with that version of pestal against Plat on my main:
6 Wins
4 Losses
4 EMs
2 Special Spin
Didn't count average ttw but it's better than Pdials
Notes on playing:
-With a good hand, rainbow decks are beatable through Vamptal after Devtal
-If you win the toss, wait till they have had a turn to play devs, or you miss out on that 1 extra quanta because they won't have any to steal
-When you have won and it's just a case of when, make sure you don't risk losing your EM by playing eclipse and killing them through devs before you vamps can heal you
-Sometimes it's better to hold back vamps so your on-field vamps will deal enough damage before killing them to get EM
