5th Gen Cover fossil or Plume fossil

[Dangelitus]

I choose archen because my starter in PW was oshawott.

Besides i found useful archeops for fly between towns and by his speed and strength.

One more reason is: I have more difficult to obtain archen via GTS than tirtouga XD.

I went with the cover fossil on my first time around. Tirtouga seemed like a cooler pokemon to me.

I had an Oshawott but I wasn't intending on using the fossil pokemon on my team anyway.

cover fossil for me just liked the design and not a big fan of bird pokemon dont really use them that often

 

[Ephemeral Euphoria]

I went with the cover fossil since I wanted a bulky water type and Carracosta fit the bill perfectly.

Even though it probably has the 2nd worst ability in the game behind truant, I always pick the plume fossil because Archen/Archeops can really wreak havoc for those few turns its HP isn't below half. While I do like Carracosta's shell smash strategy, I still prefer the risk that comes with using Archeops.

I chose the Plume Fossil, but I did not train it...

If you chose the Cover Fossil, you would end up with a Tirtouga and later evolving into a Carracosta. Carracosta can spam Shell Smash but it has a big difficulty setting up due to its low speed stat. Also, most special Grass-type attacks, especially Grass Knot, can OHKO it before it can even respond.

If you chose the Plume Fossil, you would end up with an Archen and later evolving into an Archeops. Archeops has a gigantic base Attack and a good Speed Stat, thus it can spam Stone Edge and Acrobatics if it doesn't have a held item. However, you need to take note of its Ability - Defeatist, which hinders it if its below half HP.

Up to you :)
