In this picture some more white back stamps can be found on some Energies, owned by @shizzlemetimbers
The difference: instead of getting back the same creature, you go find a new Time Lord card instead
We saw a lot of power, with double Student of Warfare / Time of Heroes nut draws and one-creature wins thanks to the fact that if we can fight through our opponent's removal and max level a creature, most of our level-up creatures can win the game by itself, but we also got Time Walked a lot of times and occasionally just played underpowered creatures (a good example of this was against Merfolk, where their creatures were often bigger and more powerful, even without the extra work of spending mana to level up)
The Good Currently bugged on Magic Online (so it reduces mana costs by two of any combination of black, red or generic mana), which makes it way more powerful than it should be (for example, we can cast a Fanatic of Mogis for free with two copies of Ragemonger on the battlefield)
Reconnaissance Mission The main issue with cards that require swinging to work is that it can be dead at times after mass removal or trying to find gas when topdecking late game
