The problem with Sweers and size in general is that it does not lock the sized unit (ie gets the benefits of the engine = extra points)
Consider Nozzle a strong, competitive level gold: Size [5] & lock for 12p and compare with Sweers, Philippa or Enslave leader ability. Makes no sense to me.
There is a whole thread somewhere in this forum about issues with size mechanics.
First: the comparison with Vigo's mozzle pretends as if balance would happen on the level of single cards. Yet it is decks that fight each other not cards. So this comparison is nonsense. Cards have to be looked at in the context of the decks and factions they are used in.
1. Mozzle is a neuetral card. Its avalible for all factions. Demanding it to be equal to faction specific solutions would be as good as demanding the end of factions.
It should never be as strong as an "in faction" conterpart. In fact one could argue the very existence of this card is tricky cause exporting control options out of control factions usually destroys the chance to ever balance the game. If each faction gains full access to the perks of the other factions the differences cease to exist synergies loose their point and everyone runs decks full of standalone units which all look the same just with different color.
2. Mozzle is a weak card and not competetive lvl. IT might have had a strong period when it was a tactic (which is again a complete other issue), but thats the past. right now 12 points for a 10 point swing is a waste of resources, unless you have some very specific requirement for your deck. The game is full of cards that generate power above their provision costs. And I haven't lost a single game, not even a turn to that card in the last 3 months(since I am here).
So much to Muzzle. Now to Seize in general. Within a "control sphere" seize is a totally balanced mechanism. But to this to work out the control sphere has have the certain qualities: under average life compared to other factions(squishiness), underaverage access to damage, harder conditions to synergies ect.. These are all present in Nilfgaard. The under average power of the units forces the control sphere to compensate by unique utilities of the cards and making use of your opponents field.
Now if I look on the seize within Nilfgaard the only really discussable thing is Damien resetting enslave. Its discussable because Damiens power is unbalancable per design.
But then again, enslave is also very predictable. Being pushed into having 8-12 tactic cards puts you in a severe disadvantage so you really rely on that ability. You provide vital information about your deck composition at the beginning of the game already. And your opponent can go full units and simply outfield you If you can't keep up with their fielding. This is even more easy with the explosion of options to field several units within a turn. Portal, units summoning other cards or cards that autosummon themselves, heroes creating card advantage: They are all "nerfs" to size. Very strong ones. The only thing you have to care about is not fielding units that give zeal on round 3 and to keep your solutions for a potential damien/defender ready when they arrive.
Maybe it is because I am a relatively new player: To me Ardal/enslave was never a real issue. I probably got most of my wins out of beating them. Portal poses a bigger threat in my eyes then an enslave.
Keeping the extra points from engines is only a real threat with the steal of high power engines. The low power engines are all easy to destroy and the decks using them swim in damage and kill them with ease is if I steal them. On top of that
the majority of them is tutorable. Quardo dwarf
, double roche or portal a duo vs a single Sweers?
I would understand if you would complain about Damien or the off faction enslave abilities, But Sweers? Please I cant take this serious. You just want cheap wins against Nilfgaard.
