Multikicker bug.
Probably not high on the list of priorities, however I randomly noticed this during the night and thought I would make mention of it, and my suspicions as to why it's happening.
If you have the mana to pay for multikicker, on something that will not automatically tap, and you tell it to kick it again, then cancel it out, it will fully refund all your mana, then if you cast it again and kick to the same stage but don't kick it, then it comes into play with 2x the charge counters (this is the extreme short of it, I did test it to the longer extremes, and I had an everflowing chalice tapping for 326 mana).
As to my theory on why this happens:
Multikicker is designed to flag the card in the games memory, and adds +1 to the flag. Problem is, when you cancel the spell cast for example, it doesn't wipe out the flags, hence full mana refund on the cancel and the ability to continuously add to the flags.
Tested on both Everflowing Chalice and Joraga warcaller.
Additional note: Flags do not clear between phases. Tried it with a warcaller, hit it up massively Main phase 1. Main phase 2 summoned it with 68 counters.
