Alms Collector: Even if he doesn't synergize with
Teshar, Ancestor's Apostle, he provides a hate piece and card draw in mono white, he is a great piece in the deck, but depending on your meta, I would consider cutting him if you don't see many wheel effects.
Archon of Emeria: This is one that you need to be careful with. Playing him early with a ton of weenies in your hand can slow your game plan down way to much. Your opponents who will be playing bigger and bigger spells will eventually overtake you. Take your time and play this when you're ready to slow it way down.
Aven Mindcensor: The satisfaction of popping this in response to a fetch land is among the best in the game. Unfortunately, his lash capability doesn't work with Teshar, Ancestor's Apostle
Boreas Charger: A little piece of ramp that can help as a sort of boardwipe protection? Damnation would be pretty bad if it read "Destroy all creatures, your mono-white opponent playing hatebears can search for 3 plains and put them into play tapped." Plus, it can come back with Teshar if your opponent is still ramping.
Bounty Agent: This is the biggest rattlesnake in the deck. Get him out, and suddenly you're everyone's best friend. If you're playing an artifact with Teshar, Ancestor's Apostle out anyways, then you can use his ability. Otherwise, I suggest you leave him on the board threatening opponents.
Bygone Bishop: Unfortunately, clue is a good source of card draw in :( So playing a bunch of weenies and getting to draw off of them later is decent value. Its not a Guardian Project but it'll do sigh
Capashen Unicorn: A Bounty Agent for artifacts and enchantments that can be brought back with Teshar. Good value.
Containment Priest: Just a good hatebear, it gets rid of the weird decks that like to do too much. Playing this card can make you the hero of the table, as it will usually only effect one player. Yess it Nonbos with Teshar, its one of those pieces you need to feel out the table before playing.
Eidolon of Rhetoric: Similar to Archon of Emeria, just watch out and dont play him too early and slow yourself down. Dump your hand, then drop this piece. (You can afford to play a little more aggressive because of the fallback Teshar provides.)
Esper Sentinel: Power creep lol. Suprisingly good card draw in mono white that triggers Teshar's first ability, and can be brought back with the second. Very good piece in the deck. (Its fun to make people pay 3 mana with stuff like Elesh Norn, Grand Cenobite).
Ethersworn Canonist: Just another piece to slow opponents down, make sure you wait for the right moment like most things in this deck, throwing him out too early can hurt you more than that one Urza, Lord High Artificer player you hoped wouldn't sit down next to you.
Fiend Hunter & Fairgrounds Warden: Functionally the same thing, just some removal that can be brought back with teshar on a small body.
Glowrider: Strictly worse Thalia, Guardian of Thraben; however, redundancy is important and this will slow down opponents WAY more than you, with your 42 creature hate deck.
Guardian of Faith: Some boardwipe protection that can be replayed with Teshar if you want to boardwipe on your turn.
Hope of Ghirapur: The best card to play against that storm player, get in for some flying damage then keep them from playing their deck. Also has the benefit of stopping counterspells, but they don't bother us too bad. As Teshar makes a Counterspell a 1 for none (technically)? Either way bring Hope back over and over till you deal 40 damage or until your opponent quits.
Hushbringer: There are currently no ETB effects in this deck; however, there are a few dies effects so watch out when playing this guy. Good luck Brago, King Eternal
Hushwing Gryff: That one but flashy and no dies ^^
Imposing Sovereign: Stops those hasty Gruul decks that like to smugly show off their Anger in graveyard (I am guilty of this).
Kami of False Hope: If you like being the most boring person in the world Cough cough Minh Juan Cough cough then play this guy over and over until your opponent wants to quit.
Knight of the White Orchid: Ramp in white on a recurable body
Leonin Arbiter: Makes fetches unplayable and hurts general tutoring alot, great piece against those combo-lovers
Lodestone Golem:Just slows the game down for everyone.
Mentor of the Meek: A really good source of card draw in a weenie deck, he's usually a large target as he can provide great sources of card draw in our deck. So its always great to bring him back with Teshar.
Mother of Runes: Mothers have a way of protecting their meanie weenies. Simple protection for any creature, also notably can make creatures unblocklable in certain scenarios.
Phyrexian Revoker: In this deck, you don't have to worry about playing him too early. As if a new threat comes out, you can just return Revoker and name the new card. It can be pretty fun to name their Sol Ring.
Ranger-Captain of Eos: Often just a white creature that draws you a relevant card on ETB. ANDDD he can sacrifice himself if you have an artifact in hand and Teshar in play. Repeating on his ETB is surprisingly powerful. If you have the budget I also suggest running Recruiter of the Guard.
Reidane, God of the Worthy Flip:: A VERY underrated toolbox card in this deck. Playing against snowlands? Play the creature side. Need to return a creature from the yard? Play the artifact side. Reducing damage by 1 and making removal cost more is extremely good when you're playing a deck that runs ALOT of silver bullets.
Remorseful Cleric: We need some sort of yard hate that doesn't hurt us as well. Also he can be returned if need be to exile yards multiple times.
Selfless Spirit: Saves your army of hate pieces from a boardwipe. Multiple times. Everytime with Teshar out.
Soltari Visionary: I have no clue if this card is good or not. It seems like a very underrated card that poses a major threat to opponents. He is among the first on the cutting block because I haven't had much time to test him out.
Spirit of the Labyrinth: Yeah go ahead, play Windfall, you won't. In all seriousness however, don't play this card out if you have a very good piece of card draw in play. If your opponents are just drawing their 1 per turn then definitely wait.
Strict Proctor: This works on ALL PERMANENTS! Lotus Cobra just doesn't work now, any lands entering wont let abilities trigger. This does make bounce lands pretty good though.
Sun Titan: Represents any hatebear in the deck that Teshar hasn't brought back. Its nice to have a larger creature in a deck full of 2 and 3 drops.
Thalia, Guardian of Thraben: The epitome of hatebear decks.
Thalia, Heretic Cathar: Nice fetchland. . . loser. Oh Nice Samut, Voice of Dissent. . . loser.
Thraben Inspector: Provides a tiny source of card advantage that can be repeated. Also on the cutting block.
Tocatli Honor Guard: Just another copy of Hushbringer.
Vryn Wingmare: Another Thalia, Guardian of Thraben.
