There's a couple different directions you can go with Priests/Teal.
My personal favorite is Tabernacle Priests which includes:
Phinehas son of Eleazar
Eleazar son of Aaron
Aaron
Ahimaaz
Eli the Priest
Dutiful Priest
Moses (not a Tab Priest but goes really well with Aaron)
Abiathar
Joshua the High Priest (he's actually Zerubbabel Temple but he's very strong in any Teal deck)
If you want to go with Solomon's Temple Priests, you would probably include the following:
Temple Priests
Amariah the High Priest
Seraiah the High Priest
Dutiful Priest
Joshua the High Priest
Phinehas son of Eleazar
Finally there's Zerubbabel's Temple:
Joshua the HP
Dutiful Priest
Joaida
plus a couple others whose names escape me at the moment.
The strongest Teal enhancements include:
Zeal for the Lord
Trumpet Blast
Burning Incense
Trumpet and Sword (mainly for Tabernacle Priests)
Eli's Sound Advice (mainly for Tabernacle Priests)
Filling Zerubbabel's Temple (mainly for Z-Temple Priests)
Gifts and Offerings
Pentecost
Scapegoat
Hope this helps!
