The second objective is about staying alive and attacking with blighted agent or Myr plus a spell that makes it unblockable until the opponent, if they do, doesn’t have spells that can counter our attacking creatures. We will use cards like
Mycosynth Fiend
as a tanky blocker to weaken the opponent’s larger creatures without our creature dying to it as Fiend gets +1/+1 for each poison counter (and even with a bad hand your opponent will still likely have some posion counters) an opponent has and Glistener elf as a cheap throw-away blocker. Normally, you would want to attack with The glistener over the myr in the first few turns due to its cheaper cost, which allows it to be played quicker. However, if a game stretches on, Myr is the preferred attacker over Glistener to to its ability of getting +2/+2 when blocked. This makes the opponent make a decision to use a spell to kill it instead of cards like Fiend or Agent (which are more important cards to be killed), block the Myr if it can be (and have a larger creature be severely weakened or a weaker creature die), or let it through and hope we don’t have pump spells. As for blighted agent, constantly attack with it and play pump instants on to it as much as possible.
