I'm pretty sure you can't, as it would fall under the following
702.12b A permanent with indestructible can’t be destroyed. Such permanents aren’t destroyed by lethal damage, and they ignore the state-based action that checks for lethal damage (see rule 704.5g).
My local Big Box had them stocked for 34.95 taxes in, which was like a dollar more than MSRP. Bought what I wanted and was happy with it. All the LGS around here are selling them for 40-50 bucks before taxes, so yeah...
The Mimeoplasm is my go to general. He's fun to pilot and is flexible enough that I can easily adjust my gameplay based on the competition at the table.
In casual events (a.k.a. everything I play), I'll suggest better plays when it's not extremely detrimental to me mid-game (e.g. are you sure you wanna block my 1/1 instead of my 6/6 with your chump blocker?). I don't mind making the game closer, but I sure as hell am not about to lose to someone who doesn't know what they're doing. I'll usually show them the things they could've done that would've put me in a worse position after the match is over.
I've played limited three times since the first Pre-release; two pre-releases and one draft. Each time I played 17 lands, each time I was fairly successful. I think for this set, the amount of lands that you need to play really is influenced by the deck you've built.
For reference:
WU Voltron/Tempo - Sealed - 5:2
WG Midrange - Sealed - 5:1:1
WR Voltron/Aggro - Draft - 3:1
Just once I want them to print cards with their promo art. That would really make my day. It's just insane how they release a card and then within a couple of months re-release the card with better art. COuldn't they just release it before with a non foil version of promo art? Damn you Rakdos Cackler for looking amazing in our promo!
When ~ Attacks, put an enchantment from the graveyard onto the battlefield.

After playing I promptly traded it for some Standard UB Control stuff.
For reference:
WU Voltron/Tempo - Sealed - 5:2
WG Midrange - Sealed - 5:1:1
WR Voltron/Aggro - Draft - 3:1
(and yes, I've realized I love white this set)
Maelstrom Pulse and Lightning Helix and Doubling Season off the top of my head were all reprinted with their promo art in MM.
