Naya Delirium is a fast go-wide aggro deck built around Wildfire Wickerfolk and Fear of Missing Out's delirium payoffs, so Eumidian Terrabotanist's landfall lifegain directly counters their clock while you set up bigger threats. Mossborn Hydra grows into a real blocker/attacker that outsizes their small delirium creatures once you've hit a couple of land drops. Trim Badgermole Cub since a 2/2 body doesn't hold the ground well against Patchwork Beastie and Wildfire Wickerfolk once delirium turns on, and cut one Meltstrider's Resolve since their sideboard brings in Pyroclasm, making a fought-for +0/+2 aura a poor investment. Note their sideboard also has Pyroclasm, so avoid overcommitting small creatures into an open board after game one.
