Come to think of it, you could do these changes :
Radek to Jalil for that DR piercing while I would generally say to use Scopica over Jalil , while on a budget that 4.5 k is not as budget worthy.
Now then, Dreen would still go to Fizzle .
This bumps your deck to 5 Stars, you have plenty of Attack Manip, DR and Life Gain, so you're putting your opponent in a tough bind.
If your opponent lets through the small fry blockers / DR's then they will take a life gap of 9 from Fizzle + Houtay , 8 from Lolly + Houtay , or 7 from Flanagan + Houtay , or 5 from Flanagan + Lolly.
Now, supposing your opponent does pill to beat over them?
It's 3 Pills to beat Flanagan, Houtay can easily have 3-4 pills plopped for the bluff or zero for a bluff (they might pill just to hope they don't take his 5 gap )
Mindy and Rodney force about 3 pills w/o attack manip 2 or so with, and they suffer an un-DR able life gap.
While Maazk is generally not considered when making a deck, he is one of the better 5's for Junkz and, in this deck, he serves a very annoying purpose, standing at another card they can't DR away without Yookie or Nova in hand, and I doubt you'll see Nova often.
Lots of walls and DR's with the DR piercing wanted, I love this deck!
