My Most Feared Unit to Play Against

So, I'm listening to my favourite youtube content creator the other day, Fritz40K. I was watching this video in particular:

and while he raises a good point about the small blast templates being way less effect then their larger counterparts, it did made me think about the Thunderfire Cannon.

As of late I have been playing against a lot of marine lists. In every single list there is at least one Thunderfire Cannon (sometimes two). This particular unit just devastates my front lines. I usually play 1000 points which I laden with tonnes of cheapies (yay! cultists!). But the Thunderfire cannon is tailor made to kill my poor zealots. I don't cry about it though because that's what my cultists are there for, right? Soak up all that barrage for hopefully two rounds to keep that thing from destroying my more expensive and powerful units before they get a chance to do anything.

So here is the thing, as I go up into the higher points in preparation for the tournament do I get rid of some of my cultists in order to take more chaos space marines in rhinos? Or should I just keep my cultist blobs? I'm going to write two lists in the next couple of days to test out each scenario, and then hopefully play them out against some Imperial Fists or Iron Hands. Do you think the Thunderfire Cannon is overrated? Do you think I'm completely off the mark? Feel free to comment and tell me your thoughts, I would love to hear what you have to say.

Attack-X Warhammer Tournament and Thoughts on List Building

So here is the link for the tournament I am working so hard to prepare for:

Guaranteed, I will be the greenest player there. But that's okay, because I'm not really going just to win. I'm not a WAAC player. I'm not a narrative player either. I'm somewhere in the middle.  So why go to this tournament in the first place? Well, to prove to myself that I can do it and hopefully to make some new friends. My small town doesn't have a lot of players, and in fact, I play the same person over and over. It will be nice to see some different playing styles, and also to experience a WAAC player with an OP army.

So then, I was thinking: should I play the flying circus (For those of you who are new to this whole 40k thing, that's daemon prince and helldrake list spam)? My ultimate decision was No. That wouldn't be fun for me at all. Making my own lists is half the fun. I don't want to play someone else's idea. I want to find the synergy within my army.

Also, screw the Meta: assault isn't dead. It is my favourite part of the game so I want a list that focuses on that.
