Now i've been thinking... A 1* filler is just a card to put there so that you have 25* with 8 cards right? So for this filler does it really have to be like a good 1* filler? Like I don't see the point of a good filler like wanda, juicy lord, massiv, malmoth etc. if it is gonna be used to lose. Now I know that some people would say "but I use the fillers to win some games before" but the thing is, is that your card would get a lot of xp if it does so that must mean that you gotta buy another one. "But what if i'm rich?" well then if you were rich than STAY OUT OF THIS! Lol jks just try to kinda look at this from my point of view. Thanks
1 star cards may sometimes need to get a win for you... this is a huge deal in elo when a win gets you say 12 points and could mean a loss of 20 points
if you have an attack reducing bonus... you need a card that will not need a pill in order to force the opponent to pill. So Uppers/Sahkrom fillers should have at least 3 power... if Montana, youd want 4 power so 1 pill forces the opp to pill lots.
finally having a 7/8 power filler means you are likely forcing the opp to pill at least 1 if they are not using an attack clan.
