My current Simic idea, having several different creatures and effect piggy-backing off one another in some way.
Hero of Leina Tower A great one drop, able to jump in power quickly with my instants and boon satyr.
Chasm Skulker Couple this with Warriors' Lesson and Dictate of Kruphix and this can get very big, very fast, not to mention it's secondary ability on death.
Courser of Kruphix A staple three drop, with a life gain, a 4 toughness, and a general pain in the ass for your opponent.
Boon Satyr Can be used as both a great creatures, or an even better bestow, able to grow any of my creatures quite quickly, on my opponent's turns.
Horizon Chimera A great flying/trample creature, with another lifegain ability, triggering on draw, giving me a nice link with this guy and Chasm Skulker
Paragon of Eternal Wilds & Paragon of Gathering Mists Made to be nice pumps for my troops, both also affect my Horizon Chimera which can get him big, fast. Also, the secondary abilities on these two really help mid-late game.
Triton Tactics A great defensive card, allows me to shutdown a pair of creatures for a turn after blocking, if i don't kill them, as putting this card on Hero of Leina Tower can pump it nicely
Warriors' Lesson A one drop draw which triggers heroic, but also can trigger Horizon Chimera and Chasm Skulker twice if both go through
Mortal's Resolve My indestructable blocker/attacker card, allows me to save an important creature, or throw mine into the fire and let it come out alive
Into the Void for mid-late game issues when I need to be able to finish off my opponent, i can just remove their creatures from the board for a turn
Dictate of Kruphix Draw cards, sure my opponent gets it too, but with Chasm Skulker and Horizon Chimera I'm ok with that.
Bident of Thassa and Bow of Nylea Scry, draw, deathtouch, what more can a guy ask for?
Looking for any FUTURE STANDARD suggestions if you have any
