I like the idea, but it seems weak to me. If you go up 10 bricks to Border Fortress, you get another 10 wall and 5 tower, but without the condition of the opposite card being new. And Border Fortress itself is already not a great card (it's in the bottom 50 most played uncommons).

To be fair, it's only existed for a week. Your comparisons do make sense, though.

Maybe add "if new: tower +20" will make it more interesting

Still too weak imo theres no reason to get this when you can get Border fortress instead

Before the recent changes I'd say the card was ok, situationally strong. But now it's a bit crappy. Here's why:
1. You can't manually add "new" flag to it with Whirlwind and Magic Portal, the only reliable option remains Renewal,
2. Cards which add new card in matching position of NF lose "new" flag after opponent's move (which was always an issue).
3. High cost prevents from "camping" for a condition to meet - the player misses many opportunities to play the card.
The card has become less synergetic and unavailable for most strategies. It's very interesting though and I think it needs some love.
Buffing it in some way would be nice e.g. reducing the cost and lowering numbers, or adding the neighbours of the matching card into condition as well.

This is all true. There are now far fewer effects that cause the opponent's entire hand to become New which was one of the more common ways to trigger this effect. This is deserving of some attention.

I see the issue, but it can provide some design space wth cards. Since its harder now to gain the new flag, cards like this can gain a buff and other cards can now place the new flag on other cards.

maybe Restoration keyword should have this (add new flag to cards) as basic ability now
