some b.s with 3star champs and items and some suggestions.
so im playing and i have a 2* warwick with cursed blade, titanic hydra and red buff. i find my last warwick for 3* on the carousel whos holding a large rod. i get back to my field and i now have a 3* warwick with a large rod, a cursed blade and red buff. my ww now has 3 items so i have no way of putting hydra back on him... not sure how you would sort this out without being able to take items off champs.
my suggestions for changes to tft are an undo button, for items (accidents happen) that you can only use during planning in the same phase you made the item of course. maybe an undo button for selling champs (only usable in the same phase you sold the champ and if you havent rerolled sinse) again accidents happen.
