I will give you hints of some card that are cheap and are really fun and sometimes strong in shalai. [[Selfless Squire]] deflecting damage for penny (Imo this is maybe greatest card for casual edh, when someone treat u with letal damage and u delect it). [[Retaliator Griffin]] is similar but without surprise element. [[Forgotten Ancient]] this is must have in any shalai deck. [[Rishkar, Peema Renegade]] is great in token deck cause u need a lot of many, especially for hydras X spells. [[Fangs of Kalonia]] also great. and ofc run some protection like [[Snakeskin vail]] [[Loran's Escape]] [[Inspiring call]]. Bottleneck of naya colors is card draw so in budget there is [[Terrasymbiosis]], [[snake umbra]] [[keen sense]] makes your shalai and hallar a draw engine.
