Voltaxic Rift Summoner

Good day to you all, i come to you for advice!, im just a casual scrub that wants to make his own builds, i dont really care for the really challanging things, i just want some advice for a build i thought up, so here goes!! i want something that uses this kind of gem setup

my current Voltaxic rift has 5Linked 1 red 2 blue and 2 green, the gems i want to use are
Melee Splash Support, Increased Critical Strikes Support, Caustic arrow, Cast on Crit, Summon Skeleton,

i also have a 4Linked Thunderfist with a red, a blue and 2 green sockets (not sure what to put in there
a Maloney's Nightfall
a Wake of destruction
and a Maligaro's Restraint at my disposal

anyone got any ideas on what to do, what to link?

i was also thinking about getting Minion instablility, but im not sure if that would work with summoning new skeletons past my limit + if its worth the point investment

really hope you guys have some good advice cuz i really wanne play this!

Greetings, Sophexis
