I just don't think that THIS is the card to freak out and take a break over. It's an 8-mana 6/5 that dies to board wipes. It's a bullshit, fatheaded beater that isn't hard to deal with at all. C'mon man, you're knowledgeable about the game. It's not like TNN came to standard. Pick your battles.
Actually, I think TNN would be a powerful but OK to print card in Standard. Supreme Verdict exists and is played, and there is less self inflicted damage in standard (no fetches Ancient Tombs, FOW, Phyrexian mana, ect) which makes him a longer clock.
My previus long break came from Coldsnap/Time Spiral- I hated Coldsnap limited, and the extra 100 some "rares" in TSP combined with me starting college made me feel priced out of Magic, so I left. I'm (likely) leaving now because the game has evolved into something that I don't enjoy. First they took away playable land destruction, then they hampered creature removal, and now they are printing creatures that CANT be removed. I'm the rare person who played in Mirroden standard pre-bannings who really enjoyed playing against Ravager Affinity, because I could run 4 main deck Detonates and Shatters, and curve out Land Destruction turns 1 (Detonate for 0), 2 (Shatter), and 3 (Stone Rain/Molten Rain). Now, you pay a minimum of 4 mana for a zero upside LD spell.
One of the main reasons I came back around ROE was because of the Pyromancer Ascencion deck. I fell in love with the deck, which was a nice skill testing deck that ran zero creatures and zero Planeswalkers (although I did have 1-4 Baby Jace in the SB), and beat you by playing a long game, turning your spells into super-powerful versions and overpowering your opponent. Following the rotation, I moved on to the Gerry Thompson Desperate Ravings powered 5 color control, which is another deck that relied on just having powerful cards, playing a long game and eventually winning.
What do those 3 decks all have in common? None of them were the best deck in the format (one of them was a Tier 2 deck, one was a rouge deck I built, and one deck fell out of favor after a while), but they all allowed me to slowly win the game through sheer persistence and overall card quality. I don't ever want to play an Esper deck- it just seems souless to me! But we are now at a point where if you want to play anything other than a midrange or aggro deck, you have to lean towards tuned machines like Esper because the creatures are just too good to beat now if you just want to durdle around. I haven't played much Standard in a while, because there are just no decks that can hold my interest anymore.
So while I view Hexproof as the flag bearer of all that I feel is wrong with Magic now, it's not just the printing of this card. The game just isn't fun for me anymore.
