When Summoned, you can place up to 3 different Synchro Monsters from your Extra Deck and/or Graveyard into your Spell & Trap Card Zone
Obviously, a four-card combo isnt the easiest to put together
(You can only gain this effect once per turn.) You can target 2 "Goblin" monsters you control, then activate 1 of these effects
Phasing Combos There are some great cards with phasing and while there arent many combos that involve phasing, there are a couple of interesting interactions for you to check out: One of the best white instants ever printed, Teferi's Protection turns these into one-sided spells: Armageddon, Apocalypse, Balance, Farewell, Wrath of God, or really any board wipe that removes all permanents
Black Zombies are in better shape with Undying returning from Dark Ascension, but were still in need of some solid two-drops
A fusion-summoned Mirrorjade will also destroy all of your opponents monsters during the end phase of the turn its sent to the graveyard by an opponents card effect, making it incredibly punishing to take out
