First of all, please read this:
http://alteil.apocoplay.com/forum/viewtopic.php?f=15&t=10411&sid=efdd5e80413f3989212ec0dc6fe9c6c4as other players have already composed an whole essay dedicated to Urgrant file
Or let me recap it for you.
Weakness of Urgrant file
1. Agi 5 Lv 4 or above unit
Since the file usually not using any agi-buff cards, Agi 5 means it can move first, if it is lv 4 or above, the returns are not usable and if it is lv 5 or above, belus also cannot engage. Therefore, urgrant file will take damage. Besides, the unit counts of the file is quite low, this will hurt the file a lot.
Ex: Afel, Dalos, Rasam, Sylph or Undine aided unit, Knight of Zero Shrine, Elite Fencer of Regus (the agi-debuff make her move first), Lebau, Awakened Erisa
2. Lack of RNG
Most unit used is RNG 1 which means this file has difficulties to hit support unit at the back. Usually, the file will use grim to remove them or tank first. But, if the grims are used up, this is a big weakness.
Ex: Solar Princess, Jack, Knight of Zero Shrine, Ex: Wizard archer of Regus, Igina
3. SP or sphere drains
Since it is a mid-big file, it needs more SP and higher sphere to operate fully. Therefore, this will slower the deck a lot.
Ex: Shade, Death Embrance, Zu, Night Wing Wyvern, Shield Coat SS
4. Removal effect and SS
Same weakness as being a mid-big file.
Ex: Deathmaker, Assassin SS, RFA SS, Wrath of Sea Lord, Disjunction
5. Damage type start/open/close/counter skill on un-removable unit
Urgrant file cannot absorb many damage at all, all is the file is using grim and kill-first method to avoid damage. Therefore, un-preventable dmg hit it a lot.
Ex: Crest Devil Knight, Zu, Alliend, Star Dragon, Jack, 3rd Emperor
6. Miracle Fruit or higher than Lv 4
Since fruited unit cannot be returned after it is closed, it causes a serious trouble for urgrant player.
Ex: Any fruited or Lv buffed Undead, Alurane, Mercenary, Angelic Knight, Violetx2
7. Grim Dependent
Drop the grims before the usage, and urgrant player will usually lose the field presence.
Ex: Ref. Citizen, Mage Knight of Regus, Talisman Mystic, Lost tome
8. Character Dependent
Nearly the full file is character.
Ex: Chase Wing, Rosa
9. Lock
You can't play any cards at all.
Ex: Pixy, punishment hole, miracle bind
Next, Some lv3 rushes depend on synergy (CMD carbs) some operate in a more independent way.
Dmg focus LV3 rush with salamanders can stand a good fight against Urgrant.
I recently won by WK high speed units and Volfied and 2 violet X2 SS
Ah... Everything's about MONEY, now that makes much more sense...
