Great input - I've yet to test out trinket mage to be honest and I most likely would give it a shot today with play testing.
Regarding nimble obstructionist - in relation to the 5 removal spells that I have, they actually also work as a pseudo 6 to 7 removal spell (as flash blockers). they can get rid of attacking mantis riders, drogskol captains, etc.
Aside from that, they are also surprisingly great against a lot of decks and could also work as a pseudo land destruction against fetch lands, not to mention a silver bullet against opposing field of ruins / ghost quarter / tec edge.
Lastly, but least likely, they can be deployed as a beater to set clocks to opponents. All in all a pretty versatile card that I love playing these days.
