When active, Tidus allows you to move your counters between creatures and facilitates card draw for dealing direct damage

The Aether Heart is a one-shot effect, but that effect is what might be the 7 most powerful worlds in Magic, Take an extra turn after this one. And just like the Marvel, it can sit around on the board for a while while generating energy, making using that effect far easier
