Hmmm… Is it now taking the mana off other cards prior to the one your cycling?
It seems to be…
Shefet disguises it a bit but with other cards it’s what seems to be happening.
It always takes from the first card in your hand, regardless of mana on the card. As far as I know this hasn’t changed
nothing about cycling changed. still the most potent deck in mtgpq. i usually win in 6 or less turns. 
Always took mana from the top card from my recollection.
Most powerful but by far the least fun deck I have. Only using it for the ‘cycle x cards’ bonus ribbons.
That is what I absolutely always thought until yesterday when I was using Nissa3 (for the first time ever) in Nodes of Power and she was not behaving the same.
Since then I’ve tried things on Kiora again and they are working how you all say. So I need to try the same things on Nissa 3 again potentially with her 3rd out. (She’s only 36 or somethinig too)
I tested this today and it looks to be unchanged.
