This complete 100-card commander deck was hand-assembled using authentic Magic: The Gathering
It is fine to put into play and fine to get just one attack out of it as well making it very effective with a large number of the cheat in cards
You might consider Stitch in Time for decks that frequently copy or rebuy spells
This should dissuade players from attacking you randomly, and serve as punishment for reaching too far
Then there are toughness-matters creatures like Doran, the Siege Tower and Baldin, Century Herdmaster, where being the Ring-bearer makes it all but unblockable
Life usually does not matter against decks like Mono-Green and UW Control, but if you suddenly are paying 12 life across this, Thoughtseize, Shocks, etc they do have access to creatures and creature lands that can just suddenly kill you
