I'm a big fan of the opportunity ability. I believe it's one of the abilities that is most difficult to counter. In can only be done with shield and triage. Even then it's not 100% effective. I like to combine summoners that give speed with opportunity cards. That's a very deathly combo :-)
I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post! 
Totally agree. Speed and opportunity are so good together, it's amazing. I remember at the beginning people were not really impressed with the water summoner but people slowly started to realize that the boost of speed plus the armor makes it an elite play for melee teams. Not surprised that his price increased a lot 😄
I agree with you. The blue summoners seemd like the weakest one at the start but it's actually damn powerful and it's not surprising that prices increase for it.
