Bug with Halo Fountain
Halo Fountain is able to activate it's first ability while tapped.
Opponent had Halo Fountain on the battle field.
I enchanted Halo Fountain with Mightstone's Animation.
Opponent attacked me with Halo Fountain, causing it to tap.
On my turn I played Runic Shot on the Halo Fountain.
opponent began activating Halo Fountain's first ability and creating citizen tokens.
Halo Fountain should NOT have been able to activate it's first ability while tapped.
In truth I would likely would have lost anyway, but my opponent Yugs, took advantage of this bug and produced an additional four citizens and attacked with them.
I have the logs from the match, and have uploaded the during and after images.
