They're all good. Every one of them is cube playable. The mechanic is broken.
Wait, what? Lutri is obviously an exception, but the others require some due diligence during drafting, so I imagine most of them will not be playable as a companion if they show up mid to late draft. So how is the mechanic broken in cube?
If you just mean having an active companion is broken, I agree with you. But for most of the cards with that keyword it won't be that easy to actually use them as companions, right?
Totally agree. Companions as an additional card in hand are obnoxious, but there is a huge gap between that and saying they are "all good" and "cube playable".
In powered cubes everything speeds up, whereas these lands slow you down. Drawing a land that enters tapped in a critical turn is backbreaking, so I will most likely pass on these tri-lands, even though it is great they are fetchable.
