The scope this card has to affect the early game against all archetypes is huge, it is able to generate tempo and card advantage simultaneously
Since damage is dealt by the creature, abilities like lifelink, deathtouch and infect are taken into account, even if the creature has left the battlefield by the time it deals damage
For a single Blue mana, you can bounce any nonland permanent
For example, were getting three versions of the UB Companion, Gyruda, Doom of Depths: I like that the Godzilla variants have a totally different name but then a reminder of the name there at the header, and even if this frame/art style isnt your cup of tea, this is a crossover
But this early edition doesnt have the drop shadow that was included in later editions
Remember that Planeswalkers don't deal any damage back to a creature that attacks it
