Vs Goblins

Sideboard:
+moment’s peace +prismatic strands
-spinneret -vines
Your goal is to not allow them to win before you build your board presence.  They cannot deal with your creatures after they reach a certain size. As with any red based deck don’t let them x for 1 you by giving burn spells a chance to take out a lord. Also, prismatic strands prevents a single color from dealing damage. Your creatures can still deal their damage if blocks were made.
Vs Affinity

Sideboard:
+gleeful sabotage +journey to nowhere
-3 hive stirrings -spinneret
Journey the atog, on site. Gleeful allows you to kill lands and any creature causing a nuisance
Vs Mono blue delver / MuC

Sideboard:
+Standard bearer +journey to nowhere
-Plated -Hive Stirrings
This will be difficult. Bearer can absorb an unwanted Snap or prevent your opponent from snapping their own creature (spell stutter sprites are often reused). You can Journey threats like a flipped delver or Spire Golem.  Consider baiting out counter spells as best you can.  Your best hope is to land as many early threats as possible and attack with everything you can.
Vs MBC Or UBC (trinket)

Sideboard:
+Standard bearer +journey to nowhere
-virulent -2 sentinel
The SB can take a critical doom blade or capsule.
Journey those crypt rats!
Vs Infect

Sideboard:
+Standard Bearer, +moment’s peace +prismatic strands
-virulent -spinneret -2 sidewinder
Use your creatures to block everything you can. Use your removal on your turn to force them to use up their protection spells without pumping. Game one is very hard but after sideboard if you can get a Standard Bearer to stick, the game should be yours. Don’t forget you can vines their creature to prevent pumping
Vs Stompy

Sideboard:
+Standard Bearer, +Prismatic Strands, +moment’s peace-spinneret
-hive stirrings -spinneret -1 sidewinder -1 sentinel
This match-up is similar to the infect match-up but you have much more time. Prismatic Strands can give you a huge edge and again a Standard Bearer or Moment’s peace really stymies their advance.
Vs Mirror

Sideboard:
+Journey to nowhere +moment’s peace
-spinneret -3 plated sliver
Journey the lords, moments peace when you can
Vs Delver Fiend
Sideboard:
+prismatic +journey
-3hive stirrings -3virulent
Journey the fiend or cyclops, your prismatic can take care of remaining threats.  You can let them expend all mana and use the strands to stop the damage. Even if it is countered, it can be flashed back. It is doubtful they will be running anything other than a dispel.
