Tobbie trumps aurelia and rick in a lot of situations.... tobbie's abilitiy really puts a hurt on non-attack manipulators. His 4 damage was HUGE when one considers Copper was running loose with his 8 damage. With Copper out of the way, Tobbie's threat is not as big as it once was.
at this point, id say mono-Sentinels is too decimated to compete, half deck options are still there:
Lehane and Melvin are still both solid ELO competitive cards... after that it all becomes a bit fragile
Tessa Cr for those that can afford her (but at 5 stars, there are probably much better ways to spend your stars).
I think Tessa is the best you can have at 5-stars at the moment. You could downgrade to 4-stars, but who would you put in apart from Coby (who is already a shoo-in for mono sentinels)? Miranda is Tessa with inconsistent damage. Zhang might be okay. But apart from those? Nobody fits the bill.
You could upgrade one of the 2-stars to Skiner but that means you have to run a sub-par 4-star.
Tobbie really sucks when faced with soa but he's not so bad when faced with higher attack manipulation cards. yuo just need pill advantage. i'm using this one deleted
