I have always thought of a way of using Thran Temporal Gateway in a Standard deck and one major reason is that I always open it in my Dominaria booster packs. The concept here is to cheat and bypass the cards’ mana costs and there is no better way than tapping just four mana. With the return of the Elder Dragons in Core Set 2019, I think it has opened a whole new batch of options to pass through the Gateway. Here below is the decklist I have come up with.

Creatures
1 Cataclysmic Gearhulk
4 Palladia-Mors, the Ruiner
3 Nicol Bolas, the Ravager
1 Chromium, the Mutable
1 The Scarab God
1 Noxious Gearhulk

Spells
1 Nicol Bolas, God-Pharaoh
2 Pull from Tomorrow
4 Thran Temporal Gateway
2 Vivien Reid
4 Gift of Paradise
2 Spring/Mind
1 Cleansing Nova
2 Settle the Wreckage
2 Ixalan’s Binding
1 Teferi, Hero of Dominaria
1 Fumigate
1 The Eldest Reborn
1 Thaumatic Compass/Spires of Orazca

Lands
1 Arch of Orazca
4 Botanical Sanctum
4 Irrigated Farmland
2 Sunpetal Grove
2 Hinterland Harbor
1 Swamp
2 Island
2 Rootbound Crag
3 Forest
1 Mountain
2 Plains
1 Field of Ruin

The Creatures:

Palladia-Mors, the Ruiner – The deck’s main hardhitter creature and can basically protect itself and can be ‘hasty’ with the gateway activation at end of opponents’ turn.

Nicol Bolas, the Ravager – With its ETB discard ability and gateway activation can get opponents to discard during their step and that you can activate its ability to turn into a planeswalker during your turn’s main phase.

Chromium, the Mutable – Another Elder Dragon option for control matchups and at times can be hard-casted as it is also uncounterable.

The Scarab God – With your mass removals dealing with the early threats, this guy can recur them late game and with enough mana. This I think is seldom to happen as my choice of removals were putting them to exile such as Settle the Wreckage and Ixalan’s Binding.

Gearhulks – the one-ofs Noxious Gearhulk and Cataclysmic Gearhulk are for situational purposes and later on can benefit from the third ability of The Eldest Reborn or that of The Scarab God recursion.

Most of the non-creature spells are used for ramping and mana color fixing along with mass removals and card draw. The planeswalkers are your additional option for the gateway drop along with single copy of The Eldest Reborn. I have though of gateway-ing Sagas are faster though the Reborn is the best choice for now.
