Well, I went out and did play with the deck in an FNM and I think my results are pretty conclusive: Not powerful enough to win, but fun enough to play.
Round 1 – Five-Color Bring to Light Planeswalker Control
… or maybe cards I own. Well, that would be too harsh, because it seemed to work. Somewhat. I think [scryfall]Kiora, Master of the Depths[/scryfall] was too much and maindecked [scryfall]Jaddi Offshoot[/scryfall] and [scryfall]Molten Vortex[/scryfall] is a bit greedy.
I did almost manage to win the first game with [scryfall]Evolutionary Leap[/scryfall], but in the end my opponent was left with 2 life and I couldn’t cobble together any offense. 0-2.
0 – 1
Round 2 – Abzan Aggro
Very aggressive build with [scryfall]Warden of the First Tree[/scryfall], [scryfall]Drana, Liberator of Malakir[/scryfall] and [scryfall]Rakshasa Deathdealer[/scryfall]. My opponent kept making mistakes and played very conservatively, but this event deck can’t really handle the quality of cards Abzan can bring to the table. 0-2.
0 – 2
Round 3 – Budget Elves
Even with budgetary limitations, the deck is actually pretty strong against me, since I don’t have anything resembling a sweeper. I was on backfoot all the time and couldn’t really attack, so I basically just waited for the [scryfall]Shaman of the Pack[/scryfall] to arrive and kill me. Again, my opponent probably played too carefully. 0-2.
0 – 3
Round 4 – Grixis Ingest
Pretty much a BfZ Block deck. I did see an [scryfall]Ugin, the Spirit Dragon[/scryfall] (which didn’t do much since I only had devoid permanents in play). My opponent couldn’t really get anything going and this was a very beginner deck. It did have some sort of theme with Ingest and Processors, but it clearly wasn’t strong enough to do anything meaningful. 2-0
1 – 3
All in All
This doesn’t really feel like a beginners deck, which an Event Deck should be. Quite a few interactions and triggers. You can get a lot of value by sequencing things well, but you’ll also miss a lot of it if you don’t play right. I probably missed plenty and missequenced plays and I’m pretty experienced (though not with this kind of deck).
You do need a better manabase. I was often one turn behind, because I had to play [scryfall]Jungle Hollow[/scryfall] on the first turn, and thus missed a one-drop. With scry that could have been manageable, but since I didn’t have that, I just couldn’t bring my stuff out fast enough. Basically, [scryfall]Llanowar Wastes[/scryfall] is a must.
It is a fun deck though. You get to do a lot of stuff, even though it isn’t necessarily that good or powerful. You are still going to lose to the [scryfall]Siege Rhino[/scryfall]s and [scryfall]Mantis Rider[/scryfall]s. Maybe this is a playable deck after the rotation. Maybe not.
I wasn’t very impressed with [scryfall]Smothering Abomination[/scryfall] which I really wanted to work, but it was just a liability most of the time. At least I got to draw a card when I had to sac it to itself.
So, buy this for the card value or to play it casually or maybe teach yourself to play better (because this does require a lot of technical skill), but don’t get this for the FNM unless you are willing to lose a lot of games.
