Triverr is a card that takes patience and skill to accommodate, but it's a very rewarding card.  It's a step up from the other triple-Satellar XYZ, Delteros, though by requiring 3 monsters, it does share the same risks.  What if they Breakthrough Skill it or, worse, what if gets Solemn Warning'd?  That's why you should have a Trap Stun (or something) handy. 

It requires 3 monsters, which is feasible for Satellars but still a considerable cost.  It recoups the resources by the random discard effect (which could either be a solid hit or simply just dump a graveyard-floater) and it replaces itself when destroyed.  But the real meat of this card is the on-summon effect of returning everything to the hand.

It gets rid of the opponent's XYZ's and bounces their traps, giving you room to deliver a 2100-ATK beating.  It also recycles cards like Fiendish Chain and Call of the Haunted (which you'll be using 3 of) in the deck.  So use Call on Vega, Special Altair from hand, Special Deneb from Grave to plus, then XYZ into Triverr, and then return the dead Call.

It's the nuclear option.  You only need one of these in the Extra Deck but Satellar players should definitely add this card to their collection.
