Multiple cards being played for no reason.

on 04/29/2017 at about 22:15CST playing in Training Grounds against SansOmega. At turn 12 SansOmega matched three Blue for 7 mana, and one for colorless. Then cast Skysovereign, Consul Flagship with a 25 casting cost. I took 5 damage due to its ability, then four (4) more were cast. Each time I took 5 damage for a total of 25 and a 60/60 creature was left. No extra mana was cast and I don't think any other supports were in play that would give the opponent 5 copies of the same card at a fraction of it's mana cost.
I have complained about this before where a card seems to duplicate itself, usually a large rare or mythic card. I have even had it happen in my favor, I had one "Imprisoned in the Moon" which I cast, then suddenly it cast two of them.
My name is Mark Gardner, log on name is weaponx71magic.
And the Training Grounds has crazy messed up match making. A level 4 against a level 53 or some such. Had a character with 32 life going up against a 112 character. What was the point of that?

But lets lock down that multiple castings for no reason glitch please.
