I'm playing soul silver and am wondering which eeveelution would best complement my Typhlosion.
Here is some information:
Now it just depends on what you want so be a bit more specific in your question.
EDIT: I tweaked it and gave more detail
To compliment Typhlosion, I would go for Leafeon. Leafeon's typing compensates for Typhlosion's weaknesses and vice versa. The pair can be a sun duo to activate Leafeon's ability and increase Typhlosion's Fire - type moves.
i would go with umbreon if yu get the right moveset it defence and sp def woul keep it from fainting longer than most evolutions
