I am now thinking in the terms of modern, but your deck should be able to do something on turns 1-3. I see that most of your curve begins with 4 mana.
About cards that cost less than 5 EUR
I would add:
4 x Birds of Paradise
- would need more untapped green source if you did it.
2-3 x Path to Exile
Also another very universal card that is not so expensive and easy to cast is Scavenging Ooze
. It removes problem cards from enemy graveyards, makes Tarmogoyf
s small while making himself bigger. I would add 3-4 pcs. If you added Oozes then Anafenza should go.
To make space I would start cuttingFiend Hunter
s - every single deck in modern kills them for 1-2 mana and the ones that do not, they do not care about this card.
Tasigurs - without fetchlands they are plain bad. I know they are very cool cards and everyone wants toplay them, but in your current deck they are not good. You can maybe play one on turn 4 by removing Lingering Souls
, but do you want it?
Also I would look forward to replace also 2-3 of the lands that come to play tapped against manlands (ie Shambling Vent
