Ok so going off this preset i am thinking of changing rowdy/ Gibson and veenyle to 2 of the Junkz 3*
So A) shud i get rid of rowdy or Gibson and why?
B) Which combination of 3* wud work best with this deck?
I think the deck lacks cohesion. There is some 2HKO combinations, some pill manips, a few high powered cards but each card is dependent on the bonus to be awesome. Hard to comment without playing with it for a few days, but I would say cut Stanly (My favourite 5* Ulu) because his ability to win a round is too dependent on both ability and bonus (in a 1/2 deck, its not that reliable. I would be happy to gamble with him in a full deck). Gaia = better than Nanook at low pill and almost as good in high pill.
This deck is not bad at all. The cards you selected are good ones.
The only problem is that your strategy is pretty straightforward: hit with the big cards (rowdy and stanley) and defend with the rest.
So to confuse the opponent more I would change veenyle to Tremorh, and Janice to Gabrielle.
