Lone Rider flips late [Investigating]

The text says “when you gain 3 or more life this creature transforms”, however the transformation doesn’t happen until end of turn. I had a 6/6 lifelinker in slot 1 and lone rider was in slot 3, the transformation should have happened after the first creature attacked and before the second, but it didn’t happen until after combat.

Oh.. So that’s how they fixed the old bug with him.. That’s not very elegant

Hi @stikxs

Can you provide more details about this issue, please?

Which PW was being used?

Thank you.

I was using Teferi, the match was the last match in the 4th stage of Avacyn’s Madness. My deck was

Creature #1 was the Ascetic, #2 was an angel stack from LA, #3 was Lone Rider. They were all buffed with Starfield’s +5/+5. I believe Archive and a flipped StV and Settle were also out, along with maybe a treasure or 2. Greg had 1 or 2 creatures I don’t remember.
