Cast creatures with a X cost do trigger Unbound flourishing but won't enter with the doubled amount of counters. The original amount of counters are put on them instead.

there's a bug with Polukranos the world eater, it shows it copie his effect 3 times but only activates then ditches the other two

May 7th, 2022. Cast Endless One for 5, should have entered with 10 counters, but only entered with 5.

Still bugged as of march 20th 2022... had walking ballista enter with unbound flourishing in play with 4 mana paid.

Expected result: Ballista enters with 4 counters
Given result: it entered with 2 counters, even though it stated x = 4 on the stack.

Basically lost me a game.

Still a bug. Hydroid Krasis and Walking Ballista won't double, even though it shows it is. X Spells still get copied, but the creatures won't double.

Apparently still bugged. Just found this out the hard way.

I also ran into this problem and would like it fixed for my deck to work properly.

Issue is still present: x is doubled on the spell, but the doubling is not applied when the creature enters the battlefield.

Just ran into this problem tonight, so this is still an extant issue.

unbound flourishing seems to be bugged at the moment, every time i go to cast a creature with x in the casting cost it shows that it will be doubled but when it enters the battle field it is not doubled.
