First, channel is very good on a legendary card since you have a way to use it if you draw a second copy
You just need any other mana source and this card helps you to fix your mana in a big way
Their product pages also include explicit unofficial proxy language and note theyre not for use in Wizards-sanctioned events, which aligns with Wizards official policy that sanctioned play requires authentic cards (judge-issued proxies are the narrow exception for damaged cards during an event)
In the case that the eliminated player was the owner of the active plane card, the next player in turn order must reveal the first card of their own or the shared planar deck and becomes the planar controller
Neither mode is particularly impressive, but pairing both on a single card makes it an interesting silver bullet for decks that might need answers to threats they cant otherwise handle, like Ketramose, the New Dawn
I also don't have any Shamans here either, weirdly
