First off, I didn't realize MaRo did this for Tempest too. This is awesome.
Tempest block is when I started but Urza's block was my favorite. I was a little too young to go out and draft those sets but I remember following every spoiler and loving every card that came out in Saga, Legacy, Destiny. I also remember my peak excitement as a child was getting a USG booster box for Christmas and cracking a Gaea's Cradle. Needed 4 of those for a deck and I didn't have the $80 for a playset (lol).
Crazy that MaRo was the only designer for Urza's Destiny. Maybe I'm misunderstanding what a designer does here, but that seems really short staffed at a time when the game was very popular.
Original Goblin General (Goblin Marshall) was very much like a Deranged Hermit and I think the tweak they made was better. I really liked the take he had on Echo + Death Triggers. I think that is just a great example of tradeoffs in the older game. It was a cool idea to staple cycling as a (2) + Sacrifice mechanic for permanents.
It would be pretty incredible if they brought Urza's block draft to Arena for an event. I think that would definitely get be back playing regularly.
