Instead of going directly in on your deckbuild, I’ll just give my general thoughts on a Ophelia deck.
Ophelia is a 50 atk dark mage with 2 effects, first and most inportant she gets +20 when supported by a tome unit, second she double orbs when she is supported by her father Odin who is ofc a tome unit. Ophelia is also best girl but thats not up for discussion obviously. This means that your deck should be focused around tome units. 50 base + 20 support + 20 from her effect means she almost always should hit 90. Being consistent 90 from turn 2 is pretty good, it certainly gives you an avantage early on.
How well this deck performs depends also on your opponents deck, if your opponent runs a lot of fliers and his lord hits 100 often it’s gonna be a tough matchup. If you do face a matchup like this your gonna need to rely on Leo5’s effect and on critical hits. Recently decks seem to play a bit less fliers then when set 2 was around so thats good news for Ophelia.
Another important factor does your opponent promote early or late? If he promotes late you have a easier game because he won’t be able to deal with your 90 lord for a while. Ophelia is a black card, so you’re gonna need to run enough black cards, Lucky for us black has plenty decent tome wielders.

This isn’t enough to make a full deck that’s why the deck should always be mixed with another color. There is plenty of choice because every color has good tome units. Here are some surgestions on cards to run. Red - Linde1&3, Lena3 and Merric4. (There is also Maria3 but her effect is a bit bond heavy.) Blue – Miriel1, Henry1&3 and Tharja1&4. White – Shara1&3, Tsukoyomi3 and Xander4 Green – Soren1&4, Illiyana3 and Shade3
The colors give different avantages so that’s up to personal preferences, you can also try making it a 3 color deck. It will be a bit less consistent but you might prefer having more options.
The weakness of this deck should be clear, with only a ‘’average’’ 20 support your units you might end up losing more battles then you would like. Should you run fliers? Fliers make your others units stronger but Ophelia weaker. Now let’s look at some nummers, being 80 instead of 90 means you will probably not win against the enemy lord unless his support fails. 20&30 supports with a 70 lord is the most common after all. On the flip side being 80 or 90 doesn’t make much of a difference when attacked by the enemy lord because he will most likely hit at least 90. Conclusion: playing fliers in the deck makes you Ophelia’s attacks fail more often but the defense stays pretty much the same, your other units get a boost in both offense and defense.
So you might wanna run some fliers and maybe you have some good cards that aren’t tome users, how many should you run? I’m not a mathmagician but here are some easy nummers. These are calculated asuming you have a promoted Ophelia on the field and still 48 cards in the deck(Meaning 6 Ophelia’s are still in the deck). This means that the chance to hit 90 increases when you have Ophelia’s or non tome units in your hand/bonds/retreat. In a deck with 50 tome units (playing 8 Ophelia’s) your chance to hit 90 is 87,5 procent. In a deck with 48 tome units (playing 8 Ophelia’s) your chance to hit 90 is about 83 procent. In a deck with 44 tome units (playing 8 Ophelia’s) your chance to hit 90 is 75 procent.
I would say don’t go below that 75%, you want to be able to trust on being 90. It’s also a bit of a mind game if your opponent sees your lord hits 90 consistent he will probably not atk your lord with units that can’t hit 90 unless he is desperate. That is exactly what we want because then it won’t matter if you fail to hit 90 if your opponent was gonna hit you either way.
Some techs I can recommend:
Black – Flora4: This deck is quite predicable for your opponent a /unpredicable/ card as flora can win you games if your opponent doesn’t expect it. Blue – Nowi3: It’s nowi I’m not gonna explain this card. Green – Elincia4: A great card to boost your whole field and she’s a flier too. Red/white – I got nothing here.
To finish this up, Ophelia is a fun deck and it’s pretty good at what it does. The avantages are: -Early promotion to a consistent 90 -Chance to double orb helps pressure. (but don’t count on it) -Almost all your units have range 1-2 -Lots of dark mages to screw with your opponents hand -Best girl Cons: -Has trouble dealing with units that hit 100 often -Predictable -Little space for techs
