­Heroes' Reunion + Aerithan, Dragon of Paradox

A 7-life instant, and an 8-mana 8/8 that... might make an infinite number of copies of itself. (But is heavily odds against it, without using goblin shennanigans)

...oh; ok - it was ''deliberately'' created as an example of bad design. While the 'gain 7 life' was presumably just an accident.

Hmm - a life gain dragon; I guess?

And... I was thinking "When ~ attacks of blocks, gain 5 life" but... lifelink covers that. So we would get one of the simplest dragons ever. I'll give it Blessing too, so it's at least fire breathingish.
