Where will you using this deck
good idee to make a low star deck to get moore points in tounment or battes
Nightmare also works at low level with Sheitane, lvl 2 Mojo, K Cube, if played with damage reduction like the Pussycats it's enough to fury with Mojo or cassio and it's game won
also the fang pi have some decent low lvl cards, Marlysa Cr, Windy Mor lvl 2, Xia Leming lvl 2, and also the La Junta cards can work.
in this style of playing it's important either to focus on high damage, good abilities and reduction or on high power and good power/attack bonuses, like the Uppers
I made a 2 star deck, for non ELO play durring tournaments.
it utalized similar qualities, though i included Wanda.
Graff is very important in a 2 star deck.
Windy Mor, Xai Leming, and Marlyssa Cr are great, since Xai Leming, and Windy Mor have 6 power at level 1, 2 and 3.
Sheitane is great, for poison, won many games for me.
then Veenyle is outstanding, 6 power, and -3 damage min 2.
I usually use a deck of 8 low star cards to get over 100 points in a daily tournament, then pop in an 8 5 star deck to let other players get points.
