Let's simplify the given expression step by step:

Given expression:
\[
x^2 + 2y^3 - 3x^2 + 1 + 5 - 4 + 3y^3
\]

1. **Combine like terms**:

   - Combine the \(x^2\) terms: \(x^2 - 3x^2 = -2x^2\).
   - Combine the \(y^3\) terms: \(2y^3 + 3y^3 = 5y^3\).
   - Combine the constant terms: \(1 + 5 - 4 = 2\).

2. **Simplified expression**:
\[
-2x^2 + 5y^3 + 2
\]

So, the simplified expression is:
\[
-2x^2 + 5y^3 + 2
\]
