Modern Horizons - fave artifacts so far

I won't lie, I've always been a fan of artifacts in MtG. When I see new set spoilers one of the first things I look for are colorless fun toys that I can use. So far Modern Horizons has not let me down. Though only a few have been spoiled so far here are my top favorites at the moment.

The Altar of Dementia. Oh now this is going to be fun sack outlet that will be replacing Ashnod's Altar in a few of my decks. Instead of colorless Mana I may or may not use I get to mill an opponent down. So in anything that produces and obscene amount of token creatures, or a deck that steals everything, this can absolutely murder and opponent in one swoop. Toss a seventy goblin tokens to the Altar and watch the other player start putting their cards away.

Now onto the swords. These are the first two teased although I'm sure there will be a few more coming along just do to the protection color combinations. Currently their combat damage to a player abilities are very nice. Got a deck that specializes in making creatures unblockable? Then these should be a no brainer to add in. I mean a +2/+2, protection from two colors and a pretty hefty extra ability for 3 colorless to bring out and only 2 to equip? Sign me up!
