need ideas for some cards in this weird partner deck

{"ops":[{"insert":"Lands:\n\nNot sure what you're budget is, but you land base needs a big upgrade. 32 is good, but in b4 its tough to run so many basics. I'm usualy not runing more than a couple. I'd also look to get rid of "},{"insert":{"card-link":"Reliquary Tower"}},{"insert":" as you don't seem to have a way to abbuse the no max hand size and keeping your top 7 cards at the end of turn is more than good enough. \n\nHere are some lands that i run in a b4 simic deck:\nBoseiju, Who Endures\nBreeding Pool\nCity of Brass\nCommand Tower\nDreamroot Cascade\nExotic Orchard\nFlooded Grove\nGaea's Cradle\nGemstone Caverns\nMana Confluence\nMinamo, School at Water's Edge\nMistrise Village\nMisty Rainforest\nOtawara, Soaring City\nOverflowing Basin\nRejuvenating Springs\nShifting Woodland\nStrip Mine\nTropical Island\nUrza's Saga\nWaterlogged Grove\nWillowrush Verge\nYavimaya Coast\n\nThye're not all needed and there's others you can play, but it's a good starting point.\n\nRamp:\n\nWith your commanders being expensive as well as the rest of your list, you're going to need to upgrade your ramp package to make it way more effecenit if you want to keep up with a b4 pod.\n\nHere's some solid options to consider I'd look to get it up to 22+ pieces and have the majority of them be 3 mana or less:\nChrome Mox\nMox Diamond\nBirds of Paradise\nCrop Rotation\nDelighted Halfling\nMana Vault\nBadgermole Cub\nBloom Tender\nKinnan, Bonder Prodigy (if you have a good amount of dorks)\nEnduring Vitality\nSage of the Maze\nSelvala, Heart of the Wilds\nSowing Mycospawn\nPir's Whim\n\nCombos:\n\nBio visionary is basically a dead card right now asit will take you a long time to assemble 3 clones , especially with low tutors. If you want to stay on it, I'd add "},{"insert":{"card-link":"Aggressive Biomancy"}},{"insert":" and if you want redundancy, "},{"insert":{"card-link":"Doppelgang"}},{"insert":". \n\nLooks like you have a few ways to make infite mana, but no where to sink it into. I'd look to add something like "},{"insert":{"card-link":"Thrasios, Triton Hero"}},{"insert":" and"},{"insert":{"card-link":"Kinnan, Bonder Prodigy"}},{"insert":" (to get to thrasios) to give you spot to sink mana into, draw your deck and win the game off "},{"insert":{"card-link":"Thassa's Oracle"}},{"insert":" \n\nTutors:\n\nBeing a combo deck, you need to have a bunch of tutors that help you find your pieces. Here's some decent simic ones:\nGreen Sun's Zenith\nWorldly Tutor\nFinale of Devastation (also acts as an infinite mana sink)\nNature's Rhythm\nTooth and Nail\nSpellseeker (often used to tutor for another tutor)\n\nI don't love "},{"insert":{"card-link":"Intuition"}},{"insert":" nor "},{"insert":{"card-link":"Gifts Ungiven"}},{"insert":" in this build because you don't have a way to abbuse them and win the game of the spot making them really pricey for something that your opponents will get to decide what they don't want to face.\n\nRemoval and interation:\n\nBeing a slower deck that;s looking to win in the late game, you need to make it to the late game. This means you'll need to stop your opponets win attemps who are playing faster decks than you. Due to this, I'd look to have 15ish pieces of interaction. Here are some good pieces to consider:\nMental Misstep\nAn Offer You Can't Refuse\nForce of Will\nSwan Song\nForce of Negation\nSink into Stupor // Soporific Springs\nPongify\nMisdirection\nForce of Vigor\nTidespout Tyrant\nMindbreak Trap\nFlusterstorm\nPact of Negation\nNature's claim\n\nHope this info helps, if you have any question on what I said, or think I made some mistakes at any point, I'm happy to have a conversation. Good luck with the build\n"}]}
