A very strange thing just happened to me in Training Grounds.
My opponent had Trostani out, as well as a flipped Legion’s Landing.
Their board was (from first to last) 1 Trostani, 5x Lifelink Soldier Tokens, and 2x Vampire Tokens.
When they matched the activate gems from Landing, 6x Lifelink Soldier Tokens were created, NOT Vampire Tokens.
The Battle log just said “Andanto the First Fort Triggered” with no mention of the type of tokens created.
It doesn’t really matter much (1/1 lifelink tokens are 1/1 lifelink tokens) but it is definitely a bug. I don’t know if it is from Trostani being out or just because there were 2 different 1/1 lifelink tokens out, though.
