Infect decks usually tend to be a lot more aggressive. Maybe add another Blighted Agent and 3 more Phyrexian Crusaders as those are your aggressive plays here? Make sure to get a playset of Glistener Elfs as those tend to end up doing a bunch of poison damage over the course of the game. I think you could add those in instead of Season of Growth, Square Up, Coretapper, and Myr Reservoir. Those all slow down your game, and Coretapper esoecially tends to do nothing at all.

The short version is that you always switch power and toughness after applying all other changes. Regardless of the order these cards resolve in, the creature will get +1/+7 and then get p/t switched.

The long version is that power and toughness effects fall into four layers (and P/T effects are layer 7, the last layer, if you have tons of different things like Control Magic in effect).

Layer 7a: characteristic-defining effects, like Geist-Honored Monk

Layer 7b: power/toughness setting effects, like Square Up

Layer 7c: power/toughness modifying effects, like +1/+1 counters or Aegis of the Heavens

Layer 7d: power/toughness switching effects, like Twisted Image

This is why Twisted Reflection can be a kill spell; you reduce the power, then swap it to toughness.
