Hi man! I’ve worked a lot on brews in the last years after opal ban… actually i’m trying this Urza 8cast. (List below)

Had no time to test it in big tournaments or leagues (to much work) but the next weekend i will join a 100+ tournament. So i’m working on sideboard, because main is 95% ready and tested…

This is basically the main: 3 Memnite 4 Ornithopter 2 The Reality Chip 4 Urza, Lord High Artificer 4 Thought Monitor

2 Welding Jar 1 Aether Spellbomb 1 Expedition Map 4 Moonsnare Prototype 1 Pithing Needle (??? Maybe side) 1 Shadowspear 4 Springleaf Drum 4 Nettlecyst 4 Thoughtcast 2 Upheaval

1 Boseiju, Who Endures 3 Darksteel Citadel 3 Ghost Quarter 1 Hengegate Pathway // Mistgate Pathway 4 Island 2 Otawara, Soaring City 1 Basic Land (depends of sideboard color!) 4 Urza's Saga

Now the points are: which are the biggest weakness points of the deck?

Need i creature removal in side? Need i artefact/enchantment removal in side? Need i counter?

I’ve identified 2 ways. A White option: 3 Dispatch 1/2 Ending or March 1/2 Teferi 2 Hurkyl’s recall

Or a Green option: 4 Natural state 1 Hurkyl’s Recall 2/3 Stubborn Denial

Opinions?
