Like majofa has said, trios are very hard to use when only pillars fuelling your quanta pool.
pendulms are a very good alternative for pillars in trios.
majofa has posted a deck for you , it's a very good choice , and i like it.
thing is, you have almost no protection, you'll most likely will get outrushed , 3 plauge and few skull shields and sanctuaries can't stop a very fast rush.
i think you should add couple of bonewalls and more plauges , more defense benefit for you from plauges, and alternative defense if you're getting rushed very fast.
i'd remove one crusader from majofa's deck, and add few bonewalls instead of vultures , that's my opinion any how.
so, basically , add pendulms , add few bonewalls, maybe few more plagues , and making it alittle bigger will help you with outdeck, and will allow you to set up defense easier.
good luck with improving your deck, regards.
