Mega Pidgeot Sand
https://pokepast.es/91e66bfe586d575a
Here's a team I built using more of the nichest mons, which is being Mega Pidgeot with it being C Ranked on
ORAS OU VR. Reasons I wanted to use it b/c No Guard is v nice, good speed tier notability outspeeding Serp as evident with speed tying Torn-T, and its good synergy with Sand. As well as the obviously fitting the Building theme. :-)
Pidgeot and Exca share the same checks with zapdos and rotom being the big ones, so with this, I went with Rocks Clef and Cofag to spinblock Exca. In theory, you can keep up rocks against them. CB Ttar is a good breaker and helps get past Phys checks of Exca and/or trap mons that would be problematic such like Slowbro or a Weavile lacking rare Low Kick, Also it helps against Zard-X with its specialized EVs and the team struggles against Zard-X. It also provides a check to Volc (broken moth) and supports Exca. Speaking of Exca, with its set of 3 attack + sub, its really well w/ TSpikes as sand, rocks and Toxic damage make good progess vs bulkier teams. Scarf wash is there for speed control for Mana and weavile, with trick helps against CM clef MU, if necessary. Thats p much the team explanation :)
