(There’s an earlier version of this card in Link Héroe del Tiempo.)
Costing Link in anything but green would feel just wrong. That’s why he is not in blue, despite destroying plants and surrounding himself in ancient mystical trinkets.
If we go by flavor, you could even argue for white/red, seeing as how he’s a crusader of peace fueled by the Triforce of courage.
Templating would mean the owner getting seven more turns instead of the opponent skipping, but as I find again and again, sometimes I need to make flavor trump wording or the effect is lost.
Mana cost and loyalty values were handwaved – the first ability is unplayable anyway. This was one of those cases where I wasn’t aiming for something a hundred percent printable, but just close enough.
