Curves covering elliptic curves with polynomially bounded genus
comment
Are there only finitely many $m$ such that $m$ is the number of elliptic curves with a given conductor?
No that's a different one. There it's said that $f$ is well-defined while I'm asking if $f(\mathbb{N})$ is finite.

The genus of the curve grows exponentially with $r$ right (assume that $C$s are all elliptic curves)?

a cover is a non-constant map with branching allowed
