I've just found/remembered there is a budget oldie from Saga and 7th:
Goblin Gardener, just in case you don't wanna spend 40+ euros/dollars for Goblin Settler.
- cons:
It must be sent to the graveyard somehow (via Jitte, Siege-Gang, Sharpshooter, or surprise blocking through Moggcatcher)
It must reach the graveyard (and not be bounced or exiled, in response)
+ pros:
It has a power of 2, in comparison to Settler.
It also has a 1 toughness (can be easily killed), and can be cast with the same mana (3R).
It's about 10 jugs of beer cheaper.
