White's two-drops in TMT clear a specific bar or they don't make the deck: the common ground stalls around 2/3 and 3/2 bodies at three mana, so a vanilla 2/2 gets outclassed by turn four and starts trading down. Action News Crew earns its slot by refusing to be only its front half. Vigilance lets it attack into that stall and still hold the fort on the swing-back, and the channel converts a late-game flood (the exact problem a stranded 2/2 has in a grindy format) into a one-sided board pump and a card off the activation.
RW Equipment and WB midrange want it for opposite reasons. RW cares about counter distribution: a 2/2 carrying Bespoke Bō already attacks as a 4/4 without tapping, and channeling six mana turns a stalled board of three small bodies into something that pushes lethal while drawing the next gas. WB cares little about the anthem and a lot about a cheap, durable body it can pitch to graveyard payoffs, which moves the card earlier in that deck's discard math (with the caveat that pitching it to something like Shredder's Revenge gets you discard value, not the channel draw: the card off the top only comes when you pay the six).
Pick it around P1P5 to P1P7 in white, earlier in a committed equipment shell, later in a white deck with a low creature count where the channel has nothing to spread counters across. Maindeck in any white deck on 17 lands; six mana is a reachable ask in a medium-speed format.
The quiet upside is against Grounded for Life, the format's best white removal, which costs more to hit an untapped creature. Vigilance keeps this one untapped after combat, bending that removal off its cheap rate while still doing the attacking a 2/2 needs to do to stay relevant.
