Three years later in 2020 the commander free spells came out with Flawless Maneuver. Now we all know which two other cards in this cycle caught the most attention, so like many, again I overlooked the potential for such an efficient way to protect my on-board focused decks from interaction. The ability to easily use this offensively is also a boon to the free cast ability. By the time I saw the light, this was also $20+ and unattractive to me because I knew it would get a reprint eventually, which it did.
After 2020 when white board protection spells started to become more prominent and available with Grand Crescendo and Akroma's Will the same year, I was determined not to miss the boat this time, so I made sure to get at least a copy or two of most every playable board protection spell that came out. Well after a couple years, they kept printing more and more variants, many more than I expected in a short amount of time. As we see in the budget section, these effects have been around for over a decade, but it's obvious that Tef.Prot. with the return of phasing got everyone thinking about mass board protection again. Along with Heroic Intervention in green. Now I have so many board protection options I couldn't hope to play them all, which is not a bad place to be, I'm just in awe of how much juice they pumped into this space in 2023 and 2024.
Today I have mono-white tokens playing 5 variants. Tef.Prot, Akroma's Will, Flare of Fortitude, Clever Concealment, and Guardian of Faith. I think 5 is overkill but my primary method of play is if I have one in hand, I can aggressively commit to the board to bait a wrath spell. Then I can save my board and keep on chugging along. I also count Akroma's Will in the win-con slot, so dedicated slot is 4 cards. The only feel bad is to have the Flare of Fortitude only to get blasted by a Toxic Deluge. Seeing Dawn's Truce sparked the thought that, maybe I have enough things that grant Indestructible, even at 2 mana, which is efficient, I could play three other cards that can cost ZERO MANA. That is some stiff competition, I mean you really cannot beat . I'll probably pick up a Dawn's Truce because it's cheap, but only 1 copy this time after grabbing 2 flare of fortitude, 2 clever concealment, and 2 galadriel's dismissal. I still like the Hexproof clause, and the mana efficiency, but if I only have 1-3 copies of this effect in my deck, I'm usually saving is for the inevitable wipe, not for a 1-for-1 trade against spot removal unless I'm desperate.
The Nitpicking Nerds had a discussion on Unbreakable Formation, and besides the requirement to hold 3 mana with no alternative cost reduction, the conclusion was Indestructible is simply not reliable enough to get a place in the deck in a more tuned list. Too many ways around indestructbile in Bounce, Exile, -x/-x, sacrifice, and more. Now I tend to agree that if I was playing in a 85% meta, say "optimized casual" I think it's Tef.Prot. and maybe Concealment or Galadriels Dismissal. Phasing is the only way to guarantee protection from the higher power wipes in the format.
Rambling aside, my questions are: Which one of these options see the most play for you? Let's remove Tef.Prot. from the conversation, as we know it is Best-In-Class and always gets first pick if you have it available. For argument's sake, you don't have one, or don't have any more copies for consideration for this discussion
