Kit Cloudkicker embodies the ideals of Tempo perfectly, putting a character into play while removing one of your opponents in a single slick move
Madam Mim, Foxs Chasing the Rabbit ability allowed me to return a character from the board to my hand, which meant I could bring back damaged ones or trigger powerful effects from cards entering the battlefield over and over - when Merlin, Goat, which gains a lore each time it enters and leaves the battlefield, turns up you can see where the game really starts
For fans of those further down the list, the set could end up missing despite the best intentions
Similarly, if Lightning leaves the battlefield and later returns, you won't be able to play the cards that were exiled the first time it was on the battlefield since it's a new object
When that creature dies this turn, return that card to its owner's hand
Also, keep an eye out for the DISSIDIA FINAL FANTASY COLLECTION SET coming later this year, as Shinryu [20-127L] might have synergy with some of the cards in there
