https://deckstats.net/decks/108636/1374631-syr-konrad-s-merry-go-roundHey, so here's my entry; one uncommon Commander and rest have been printed as commons at least somewhere.
The gameplan here is to use cycling and sacrifice effects to get an engine going for Syr Konrad.
First turns are spent smoothing out the draws and gathering value. Eventually one should have bunch of creatures in the graveyard that allow for heavy life loss with
cards like
Forever Young and
Gravepurge if Syr Konrad is out.
Phyresis is especially nasty on our commander, since one decent pile and possibly a couple of activations
are all it takes to poison people out.
Horror of the Broken Lands can also do some damage with
Restless Dreams, even though it's even more insane with the commander if you're
discarding creatures and also fetching them out at the same time.
If everything else fails there's always the plan to beat face.
Silumgar Scavenger can grow to a decent size with sacrifices and there are other flying creatures in the deck as well.
Possibly some of the
unearth mobs might also surprise unprepared enemies. Three of the cards have transmute on them, so those can be used to tutor up
Forever Young /
Phyresis,
one of the good 4 drops (like
Pestilence) or Gary.
Land count is quite low but with all the draw options and by knowing when to mull it should turn out fine. Average CMC is also a bit higher than in "reality" since many of the cycling spells
aren't meant to be hardcast early.
