When playing Brawl with Samut as my commander if my speed is already at 1, he brings it up to 2. This isn't supposed to happen. Playing additional "start your engines" cards shouldn't raise my speed past 1. Furthermore, one the same playing Samut brings my speed up to 2, if my opponent loses life it will go from 2 to 3. My speed isn't supposed to be able to increase more than once in a turn.

If I cast Samut with my speed already at 4 it will still display the speed graphic and make the noise as though my speed were increasing even though it's already at 4
