I think this should be moved to the "spells" section rather than suggestions
I'm sure [mwcard=FWC04] Goblin Builder[/mwcard] suck so much because they were too good in some obscure combination which never came out.
Here are some things they are good at:
non-legendary(6 out at once), not mage exclusive
cheap: 5 mana, level 1
comparable to goblin grunts(1 more mana, 2 more life, one less damage, pest)
the only conjuration familiar
one of only two things which can heal (nonliving nonskeletal) conjurations
The power of goblin builders is based on the power of conjurations. because most conjurations are zone-exclusive, these builders only spend every second turn building something, which is the dealbreaker for most people. As more conjurations come out for all mages, these builders will become better. If good non-Zone-Exclusive conjurations come out for non druids, these guys will rock without any changes.
Current non-zone exclusive conjurations i would use for them(I'm not counting [mwcard=DNJ08] Seedling Pod[/mwcard] or [mwcard=DNJ06] Nightshade Lotus[/mwcard]):
[mwcard=FWJ06] Mangler Caltrops[/mwcard]
Walls including: [mwcard=FWW01] Wall of Pikes[/mwcard] [mwcard=MWSTX2FFW01] Wall of Earth[/mwcard]
[mwcard=MW1J15] Mohktari, Great Tree of Life[/mwcard]
[mwcard=DNJ02] Corrosive Orchid[/mwcard]
I would enjoy one of these overpowered changes:
1)Can repair walls, which isnt a big deal, except for regenerating armored walls(which could heal 8 damage per turn from creatures)
2)Some way to allow them to build 2 zone exclusives in a row(can move after building, can build as a quick action, let them build at range, ect)
3)Let them "pray" at the construction yard for one mana like priests do at altar of skulls
4)Casting him is a quick action like tataree
I am curious to see how these builders will interact with upcoming terrain. Unless terrain is "attached" to a zone, they may need an errata.
now that i've thought about them, I'm going to dream up a book that uses conjurations(from builders) to block and ranged creatures to damage.
