Should I Add/Drop?

My team currently is:

• Quas
• Jankos
• Froggen
• Forgiven
• Nyph
• MrRallez
• Elements
• PowerOfEvil
• Fredy
• Airwaks

I feel pretty good about my drafting, but I saw that Lustboy and Fenix haven't been picked. Two guys who probably will have good years. Lustboy for being on TSM and duo-laning with WildTurtle and Fenix for being on a team that looks promising and could rack up a lot of kills/assists. Do you think I should trade? PowerOfEvil for Fenix? (since I can only have two mids) or another player for Lustboy? I'm not too sure about Airwaks since I'm a little less into lower EU teams but his estimated points this week are pretty high. (playing against H2K and Giants). Tell me what you think so I can GG EZ NOOBS this Fantasy LCS. Thanks!
