if you want it to be more controlling you should play a few more counters and the counters you are playing aren't great most counterspells are relatively cheap. I would say
Counterspell of course I think it should already be in the deck,
rewind,
sinister sabotage even at 3 mana is pretty good. If you go that route you should play baral I think he has a place in this deck regardless of whether you add more counters or not. also bigger draw spells like
pull from tomorrow and
stroke of genius might be good if they fit in to your budget. Also Blasphomest Act you should play as a board wipe although it is like $4. but seems cool.
