not to be rude... and also the fact that i just joined the site. but i think most of your problems is your all trying to make triplets your main focus.. the center of your decks. try using them as the end result or the fall back, make it more of just plain control. this is one of the 2 triplets decks im running currently..

4 ethersworn canonist
4 sphinx sovereign
4 orims chant
2 tezzeret
3 master transmuter
4 echoing truth
2 scourglass
1 dralnu lich lord
1 goblin welder
1 tinker
1 demonic tutor
3 sen triplets
2 arcane denial
2 iso scepter
1 walk
1 recall
2 averice totem
1 twister
and last but not least.. only for a joke
1 hanna, ship's navigator  lol

the last card was just for fun.. but somehow she works

this is one of 2 i have, this is more for group play i have another thats more one on one
i hope i was of some help
