How is this for an Arena Core Team?

Its shit, no fliers means no guidance maneuverability, no healer means no keeping bonus units alive. Overall severe lack of proper ally buffing ability.

1/10, Apply yourself.

Arena has shifted toward support units. As such these units arent the best for that purpose.

Units that have support abilities built into their weapons are better as arena core units, such as cherche, jafar, sothe, soren, MCorin and such

Nilla could have phrased it more constructively, but I would add in either a maneuvering ability (such as a Guidance flier or dancer) since the units you’ve shown only have rally skills or a healer (though I doubt one would synergize well with your team in this case).

I’d also take advantage of infantry exclusive skills like Infantry Pulse and Wrath.

You’ve got the components, you can do this!!
