Just to chime in: I didn't play the first iteration of the Legendary Cube, but the one that was up most recently was, in my opinion, a super fun format. Obviously there were a few "mistake" cards in the mix, but for the most part, I actually had a really fantastic time drafting it, moreso than any other MTGO cube offered so far. I wish I had had more time to draft it, but, I'm really looking forward to the next iteration, and I'm looking to it for cues for potential includes in both my main list and a new side project I'm exploring. I usually really take issue with MTGO cubes, but this format was one I couldn't get enough of, personally! One of my favourite takeaways:
Xiahou Dun, the One-Eyed; that card really overperformed for me, and in one round I had a ridiculous engine between Xiahou,
Mimic Vat, and
Annihilate. Good times!
I don't it really needs to be said, but from the amount of drafts I did, you can tell I really enjoyed the format.
From the previous iteration they did a good job of reinforcing the 'battlecruiser' style magic they were aiming for with this cube. Taking out a lot of fixing and mana rocks was met by disdain from a lot of people but has really diversified the format.
I may be a little too impartial to the enchantment archetype (it shall forever be known as
Opalesence to me), but all the support they gave to allow these random archetypes to be born was great and I hope that they refine these down by cutting the chaff they gave to make some of them work (but in reality don't help at all) in the next iteration.
I did a Legacy Cube draft just before and played some BG reanimator deck. Sure,
Recurring Nightmare with
Thragtusk still seems like a fun way to play games, it just didn't feel the same. I guess it was refreshing to have a format where haste was so powerful, removal was premium and planeswalkers were at a minimum.
Makes me want to see if I can make my own version of a battlecruiser cube.
Only one target, Horobi gets sacrificed on targeting, after Horobi dies, Verdant Confluence has no legal targets left and gets countered by state-based effects.
I've used bugs in MTGO to help me machine gun down so many creatures with Horobi (sort of unintentionally). The first time was in a 3 x CHK draft, where I dropped it with one mana up for
Waxmane Baku (only had one counter). Wanted to kill his big thing, but noticed MTGO would let me select more than one target. So I clicked on everything, chose not to remove any counters and blew up his board. I don't think it was intended to work that way, but I'll take the win (he can file for reimbursement I guess).
The second time was in the Legendary Cube, where I had a
Marath in play, opponent played Horobi and I thought, I wonder if the errata on Marath actually works (x can't be zero). No, no it doesn't. So I just try and throw 0 +1/+1 on all his creatures to blow them up at the end of his turn.
God, you have to love MTGO.
