Back again with another list of cards to consider now that Throne of Eldraine is out. There are a lot of interesting White cards in this set, though unfortunately not many that are of use to Teshar.
Acclaimed Contender: Pretty good card filtering, but only works if you control another Knight. I don't run many Knights in my list, but if you're going for more of a Knight theme, this is pretty good.
Charming Prince: Its a charm! On a creature! Problem is the modes just aren't useful for this deck. Scry 2 is okay at best, 3 life is near useless in EDH, but an end-of-turn flicker is good if you're piling on a lot of ETB effects. In my list, he just isn't worth it.
Giant Killer: I really want to put an Adventure card in here because the alt art is all phenomenal. Problem is none of the White cards have worthwhile ETB effects, and the Adventure half is useless once the creature is in your graveyard, which is where most of the creatures in this deck aim to be.
Happily Ever After: 5c wincon, no use here.
Harmonious Archon: IMost of the creatures in this deck are 3/3 or less so the downside won't hurt us much. Comes in with two tokens that also turn into 3/3 as well. I'd love to find a slot for this guy, but he's over 3CMC and isn't legendary so I'm finding it difficult to cut something for him.
Hushbringer: A great hatebear, problem is it prevents the two things this deck does most: Triggers on ETB and death.
Linden, the Seadfast Queen: 3CMC, Legendary, problem is the effect is less than useful for this deck.
Mace of the Valiant: This is kind of interesting. Equipment gets more powerful the more ETB triggers you have. Could be a good way to close out a game, but I feel like people will get wise before it gets big enough to really do some damage.
Realm-Cloaked Giant: I love my boardwipes, but 3WW for a
Day of Judgment with limitations just isn't good enough to cut one of the wipes already here, even if you can cast a 7/7 vigilance later.
Silverwing Squadron: We usually don't have many creatures out, even if this does make itself bigger every time it attacks. Especially for 6 mana, this just isn't worth it.
Syr Alin, the Lion's Claw: If you're going aggro/swarm this guy may be worth a shot. In my case, I don't think so.
The Circle of Loyalty: While I don't have many knights, I am casting a fair amount of legendary spells. If I can get my hands on one of these I may give it a try.
Worthy Knight: Great if you're going for a Knight theme again, otherwise not really useful.
Castle Ardenvale: We'll have no problems overcoming the untap limitation here. I'd say it's worth a spot as a late-game mana sink and we aren't really starved for space for nonbasic lands.
Fabled Passage: An
Evolving Wilds that allows the land to come in untapped later in the game. Could be good for land thinning?
Heraldic Banner: A
Manalith That will also give any White creatures +1/+0. Good in a budget deck I'd suppose.
Idyllic Grange: it's a Plains, which we have no problems tutoring for, and a free +1/+1 counter is always welcome. Only downside is it you happen to draw it before turn 4 with no other lands. I'd say this is worth a spot in most cases.
Inquisitive Puppet: If his effect was on Sacrifice instead of Exile, this would totally be worth it.
Stonecoil Serpent: I'd say this gives
Hangerback Walker a run for its money. Half the cost, and comes with a hefty number of keywords rather than making Thopters on death. I think I'm going to try this one out.
Tome of Legends: I don't attack with Teshar very often unless there's a distinct lack of flying blockers on the table. That being said, a cheap source of draw isn't exactly unwelcome.
Witch's Oven: A sac outlet, but requires a tap. I feel like there's some way to break this to our advantage, but I can't think of one.
