In Round 5 Underworld are joining the War. RR has a match against this unknown entity and it may be useful to have a look at what they bring.
First up, they have modified deck building rules:
Team Underworld is basically "Team Rainbow", so their deckbuilding rules differ from other teams.
Modified deckbuilding rules for Team Underworld:
- any mark
- maximum of 3 copies of a single card. This restriction does not apply to Pillars or Pendulums.
- non-upgraded cards only. Upgraded cards are not allowed.
- General may use up to 6 upgraded cards (unupgraded cards taken from the Vault are transformed into upgraded ones)
- Lieutenants can use up to 3 upgraded cards (unupgraded cards taken from the Vault are transformed into upgraded ones)
- no Shards
- players are not allowed to change their decks during a round.
The important part is in bold. I shall be trawling through their tournament this year and their decks from last year to have a look at what decks we might be facing.
