I've 100% Variant 4.
Thankfully I didn't sell any of my 1* so that 1* champ restriction chapter was ok and smooth and definitely fun. Props to KABAM for that.
But it got me thinking for those that sold their 1* champs prior to this Variant was out.
Take a look at this pic and decide it yourself.
PS: Pardon my wrong word usage. Should be 'probable' instead of 'probably'
