I never imagined that two of the hobbies that carried me through high school would come together like this, but I am so glad that they did
If you go down this path, make sure to balance cheaper artifacts with threats like Furnace Hellkite
Connive allows you to draw then discard a card, and if you discard a non-land card, you may put a +1/+1 counter on that creature
While it's never seen any real competitive tournament play, as far as I can recall, it's just such a cool creature, and I love adding it to Cubes
We have a bunch of viable 3-mana artifacts that can ramp into Ugin (and then trigger his static ability to exile an opponent's card once he's in play) but don't forget about Hedron Archive as a low cost way to jump from 4 to 6 mana (7 with your land drop)
The other possibility is playing Invasion of Regatha in a dedicated burn deck since the backside seems pretty powerful with Play with Fire, Lightning Strike, and friends as a weird twist on Torbran, Thane of Red Fell, although I'm not sure a burn deck wants to use multiple burn spells or attacks to remove the five defense counters to defeat the battle
