Monster Exploit(s) Available In M:tG Arena MMR

Not just the “concede a lot for easy pairings” idea detailed in Inside the MTG: Arena Rating System, which still works quite well, as another Ivana 49-1 cakewalk from Plat 4 to Mythic the past couple of days would attest, but this time exploits that can be used for the top-1200 race itself.

In Bo3, conceding on the sideboarding screen ends the match *and only considers previous games when rating the match*.  Conceding down 0-1 makes you lose half-K instead of full-K (Bo1 K-value is ~1/2 Bo3 K-value).  If the matchup is bad, you can use this to cut your losses.  Conceding at 1-1 treats the match as a (half-K) draw- literally adding a draw to your logfile stats as well as rating the match as a draw.  If game 3 is bad for you, you can lock in a draw this way instead of playing it.

If you win game 1 and concede, it gets rated as a half-K match WIN (despite showing a Defeat screen).  This means that you can always force a match to play exactly as Bo1 if you want to- half K, 1 game, win or lose- so you don’t have to worry about post-sideboard games, can safely play glass-cannon strategies that get crushed by a lot of decks post-board, etc.- and you still have the option to play on if you like the Game 2 matchup.

Draws from the draw bug (failure to connect, match instantly ending in a draw) are also rated as a draw.  I believe that’s a new bug from the big update (edit: apparently not, unless it got patched and unpatched since February- see the comment below).  It’s rated as a normal draw in Bo1 and a half-K draw in Bo3.

    No, this has been an ongoing issue for a while– possibly since the beginning of Arena, though I’m not sure. It’s especially prevalent now, as server issues seem to have increased the frequency of the “failure to connect” draw bug recently.

    See this Brad Nelson tweet from February for more evidence: https://twitter.com/fffreakmtg/status/1362442709135331329
