During a game I dropped parade leader out and then used Runic Carvings to summon 4 rush totems. I had 7 mana and carvings was 5 mana due to a Nature studies that was used a few hands prior. Parade leader did not buff +2 attack to any of the rush totems (4 of them) that were summoned. Clearly this is a bug?
It was me vs another druid. He dropped Silas Darkmoon the previous turn.
Thanks
